Quantitative and Qualitative Data collection methods
INTRODUCTION
Overview Of Different Data Collection Techniques

Web-based interviews, on the other hand, make use of the internet to gather information so you will not have to the field for it. This latter method is also less costly and more convenient to use. Telephone interviews are very much similar to face-to-face interviews, but they are shorter in comparison and more structured. You may also have to send a letter to inform the interviewee in advance so they would expect your call. Surveys and Questionnaires Both are popular means of gathering data and can reach a large number of people, but they need to be designed and reedited repeatedly to make them acceptable to people.

You can either print out copies to hand them out to people or send them to your respondents through email. Though this method is relatively cheap to conduct and requires no prior arrangements, surveys and questionnaires have the risk of low response rates and some may turn out to be incomplete.

Focus group interviews and consumer panels Gather a group of people, specifically from your company's target market, and have a facilitator guide them in examining a certain product and asking their opinions on said product. This method is primarily used to determine whether a company's new product or brand name will be acceptable to their target market and to the general public.

Observation Observation is one of the simplest methods for primary data research and would not cost much. All you have to do is simply take note of the behavior of people towards your company's products and services.

You can also try to observe how your competitors behave, and how they provide their products and services.

Make sure that you are not alone in observing and have a number of colleagues to do the same thing so you can differentiate between fact and opinion.

Collecting primary data maybe difficult and may take a long time to finish, but the end result is that you have the necessary information you can use to make improvements to your company's products and services.

What is registration method in collecting data? This is just a simple question tapos di nio masagot-sagot ano ba kau huh, Compare Quantitative and Qualitative Data? Quantitative data is measurable and numerical in nature. Incontrast, qualitative data is any data that is not numerical andcannot be measured, only observed.

Examples of quantitative datainclude age, height, year, and population. Examples of qualitativedata include color, gender, country, and city. What are some examples of quantitative data? Quantitative data is data that measures quantity, as opposed toqualitative data which describes quality. Some examples ofquantitative data pertaining to weather would be: Quantitative data uses numbers to measure observed changes how could this experiment be modified so that quantitative data could be collected to show that waqter diffused into the dialysis bag?

Mass the bag before and after its exposure to the solution. If diffusion occured, then there should be an increase in the bag's mass. Qualitative data and quantitative data? Quantitative research In the social sciences, quantitative research refers to the systematic empirical investigation of social phenomena via statistical, mathematical or computational techniques.

Qualitative research Qualitative research is a method of inquiry employed in many different academic disciplines, traditionally in the social sciences, but also in market research and further contexts.

Qualitative researchers aim to gather an in-depth understanding of human behavior and the reasons that govern such behavior. The qualitative method investigates the why and how of decision making. Show example of quantitative data? An example of quantitative data would be the number of people born in 1 hour. Method of collecting data in statistics?

Your question is very general. I will give you some suggestions and perhaps you can rephrase your question to a specific problem. I believe the question can be rephrased to how a statistician may approach obtaining valid data for the purposes of interpretation. Generally, data is collected with the purpose of making inferences to a larger population which can not be surveyed. So, in statistics, the key to collecting data is that it is representative of the larger population that you are interested in.

The statistician has choices to make in a planned observational or experimental study. The simple random selection may be appropriate in many cases, for example, in a quality control situation, where a sample of parts from a larger batch of parts are selected and tested.

More complex sampling schemes are possible, still with the intent that the data can provide a significant, meaningful understanding of the population. The means to reduce biases in these surveys is very important. Data can be complicated, and may not tell the full story. For instance, let's say that one road has a high number of accidents. Is it a problem of the road condition, the drivers that use that road, poor signs, too many exits, etc.

In this example, statistics and other information can help point to the most important factors. It should be noted that surveys are not the only way of collecting data. In education, data may be in the form of tests scores, GPA, etc.

The list of alternatives to survey research is extensive, but in all cases, the principles of random sampling and statistical assumptions still apply.

What are the advantages and disadvantages of data collection methods in statistics? There are both advantages and disadvantages of data collection methods in statistics.

The main advantages are the metrics and correlation one can draw from statistics. The disadvantages stem from sampling errors. What does quantitative data mean in maths?

The opposite is qualitive data and this would be opinions. Importance of quantitative methods? Quantitative methods of studying are important because they givegreater picture ideas of a population.

This means that the datacollected is a more accurate picture of what is going on in thepopulation. What does quantitative methods mean? Examine advantages and disadvantages of empirical methods of data collection? Empirical methods mean those which use experimentation to determine or estimate actual values, be it frequencies "how many" or relative proportions. This is good because these experiments are observable, able to be confirmed, and easily replicated.

Too often, short run experiments too few number of trials result in invalid conclusions. What is a descriptive quantitative study method?

A descriptive quantitative method is analyzing data between twothings or an outcome in a population only one time. There is alsoexperimental quantitative studies where the subjects are analyzedtwice, before and after a treatment.

Why choose quantitative method? What is quantitative data analysis? Any type of analysis that deals with numeric data numbers is quantitative analysis. Qualitative analysis, on the other hand, does not have numeric data for example, classify people according to religion. What are the five methods for collecting data? There are a variety of methods used for collecting data. Theseinclude registration, questionnaires, interviews, directobservations, as well as reporting.

What is the definition of qualitative and quantitative data? The way I remember it is that Quantitative data includes quantities Qualitative data describes qualities Which is the appropiate method To collect data from a busy manager? Have him email it. He can then choose what time he does so delegating the task if he wishes. Why do we study quantitative methods? It is important to study quantitative methods to learn to doresearch.

It is very important to keep in mind that, inquantitative methods, correlation does not mean causation. How should data be collected and displayed in the scientific method? The scientific method does not detail how you do an experiment, only the method used in general terms. How data may be qualitative or quantitative?

Difference between quantitative and quantitative data? If you mean qualitative and quantitative data, then data would be dealing with numbers to describe a statistical analysis whereas qualitative represents things that cannot be expressed as numbers such as color. Is western blot quantitative method?

Western blot can be semi-quantitative. This means that you cannot determine absolute protein levels, but you can detect differences between groups. For example, if you have 4 different samples, a western blot will be able to tell you which samples have the most of any specific cellular protein. What are some biologial methods used to collect biological data? Learning and building knowledge is a natural inclination for human beings. Even at a very young age, we are in search for answers to a lot of things.

Take a look at toddlers and small children, and they are the ones with so many questions, their curious spirit driving them to repeatedly ask whatever piques their interest.

A toddler curious about a white flower in the backyard will start collecting data. He will approach the flower in question and look at it closely, taking in the color, the soft feel of the petals against his skin, and even the mild scent that emanates from it. He will then run to his mother and pull her along until they got to where the flower is.

And now the little boy even has a name for it. Suddenly, he felt a prickle in his fingers, followed by a sharp pain that made him yelp. When he looked down at his palm, he saw two puncture marks, and they are bleeding. The little boy starts to cry, thinking how roses, no matter how pretty and good-smelling, are dangerous and can hurt you. The same goes in case of a marketing research, for example. A company wants to learn a few things about the market in order to come up with a marketing plan, or tweak an already existing marketing program.

Leaders cannot make decisive strategies without facts to support them. Planners cannot draw up plans and designs without a basis. Entrepreneurs could not possibly come up with a business idea — much less a viable business plan — out of nothing at all. All that decision-makers are left with is their intuition and gut feeling , but even gut feeling and instinct have some basis on facts. Decision-making processes become smoother, and decisions are definitely better, if there is data driving them.

In business, one of the most important decisions that must be made is on resource allocation and usage. If they collect the relevant data, they will be able to make informed decisions on how to use business resources efficiently. Just as having data will improve decision-making and the quality of the decisions, it will also improve the quality of the results or output expected from any endeavor or activity.

For example, a manufacturer will be able to produce high quality products after designing them using reliable data gathered. Consumers will also find the claims of the company about the product to be more reliable because they know it has been developed after conducting significant amount of research. Through collecting data, monitoring and tracking progress will also be facilitated.

This gives a lot of room for flexibility, so response can be made accordingly and promptly. Adjustments can be made and improvements effected.

Now we move to the next question, and that is on the manner of collecting data. Why is there a need to be particular about how data is collected? Why does it have to be systematic, and not just done on the fly, using whatever makes the data gatherer comfortable? Why do you have to pick certain methodologies of data collection when you can simply be random with it? You may notice some methods falling under both categories, which means that they can be used in gathering both types of data.

Exploratory in nature, these methods are mainly concerned at gaining insights and understanding on underlying reasons and motivations, so they tend to dig deeper. Since they cannot be quantified, measurability becomes an issue. This lack of measurability leads to the preference for methods or tools that are largely unstructured or, in some cases, maybe structured but only to a very small, limited extent.

Generally, qualitative methods are time-consuming and expensive to conduct, and so researchers try to lower the costs incurred by decreasing the sample size or number of respondents.

This is considered to be the most common data collection instrument for qualitative research, primarily because of its personal approach.

The interviewer will collect data directly from the subject the interviewee , on a one-on-one and face-to-face interaction. This is ideal for when data to be obtained must be highly personalized. The interview may be informal and unstructured — conversational, even — as if taking place between two casual to close friends.

The questions asked are mostly unplanned and spontaneous, with the interviewer letting the flow of the interview dictate the next questions to be asked. However, if the interviewer still wants the data to be standardized to a certain extent for easier analysis, he could conduct a semi-structured interview where he asks the same series of open-ended questions to all the respondents.

But if they let the subject choose her answer from a set of options, what just took place is a closed, structured and fixed-response interview. Focus groups method is basically an interview method, but done in a group discussion setting. When the object of the data is behaviors and attitudes, particularly in social situations, and resources for one-on-one interviews are limited, using the focus group approach is highly recommended.

Ideally, the focus group should have at least 3 people and a moderator to around 10 to 13 people maximum, plus a moderator. Depending on the data being sought, the members of the group should have something in common. For example, a researcher conducting a study on the recovery of married mothers from alcoholism will choose women who are 1 married, 2 have kids, and 3 recovering alcoholics.

Other parameters such as the age, employment status, and income bracketdo not have to be similar across the members of the focus group. The topic that data will be collected about will be presented to the group, and the moderator will open the floor for a debate. This method involves the use of previously existing and reliable documents and other sources of information as a source of data to be used in a new research or investigation.

This is likened to how the data collector will go to a library and go over the books and other references for information relevant to what he is currently researching on. In this method, the researcher takes a participatory stance, immersing himself in the setting where his respondents are, and generally taking a look at everything, while taking down notes. Aside from note-taking, other documentation methods may be used, such as video and audio recording, photography, and the use of tangible items such as artifacts, mementoes, and other tools.

This is a research or data collection method that is performed repeatedly, on the same data sources, over an extended period of time. It is an observational research method that could even cover a span of years and, in some cases, even decades. The goal is to find correlations through an empirical or observational study of subjects with a common trait or characteristic.

The study aimed to gather data on the characteristics of gifted children — and how they grow and develop — over their lifetime. Terman started in , and it extended over the lifespan of the subjects, more than 1, boys and girls aged 3 to 19 years old, and with IQs higher than However, the strength of a case study as a data collection method is attributed to how it utilizes other data collection methods, and captures more variables than when a single methodology is used.

In analyzing the case study, the researcher may employ other methods such as interviewing, floating questionnaires, or conducting group discussions in order to gather data. Data can be readily quantified and generated into numerical form, which will then be converted and processed into useful information mathematically. The result is often in the form of statistics that is meaningful and, therefore, useful.

Unlike qualitative methods, these quantitative techniques usually make use of larger sample sizes because its measurable nature makes that possible and easier.
