Types of research data

Interval and ratio data measure quantities and hence are quantitative. The researcher who decides to use such a scale in their study has to make another set of judgments: The researcher who decides to use such a scale in their study has to make another set of judgments: Data Sources Below is a list of general data sources.

And, it obscures the fact that qualitative and quantitative data are intimately related to each other. The simplest way to do this is to divide the qualitative information into units and number them. The best way to determine central tendency on a set of ordinal data is to use the mode or median; the mean cannot be defined from an ordinal set.

A person can also have an age of zero. This may appear ordinal but is not -- these are used to simplify capture and referencing. Primary data actually follows behind secondary data because you should use current information and data before collecting more so you can be informed about what has already been discovered on a particular research topic.

Classification of Data There are multiple classifications of data that we used in our research these include, discrete data, Ordinal data, Continuous data, Nominal data, Interval data and Ratio data. On the other hand, all qualitative information can be easily converted into quantitative, and there are many times when doing so would add considerable value to your research.

Example My level of happiness, rated from 1 to The only thing a nominal scale does is to say that items being measured have something in common, although this may not be described. The resulting matrix or table describes the grouping of the ten statements in terms of their similarity.

Temperature, in degrees Fahrenheit. The only thing a nominal scale does is to say that items being measured have something in common, although this may not be described. Letters or other sequential symbols may also be used as appropriate. Pay bands in an organization, as denoted by A, B, C and D.

For instance, think about a very common quantitative measure in social research -- a self esteem scale. Olympic judging scores 6. These are commonly used on arbitrary scales, such as scoring your level of happiness, although such scales can also be continuous.

Personally, while I find the distinction between qualitative and quantitative data to have some utility, I think most people draw too hard a distinction, and that can lead to all sorts of confusion. The reliability and validity of the results depends on upon proper selection of the research approach and design.

Founded as the American Religion Data Archive in and going online inthe initial archive was targeted at researchers interested in American religion. Regardless of the purpose of the research, the process is similar. What may look like a simple, straightforward, cut-and-dried quantitative measure is actually based on lots of qualitative judgments made by lots of different people.

For many of us in social research, this kind of polarized debate has become less than productive.

This type of data typically comes from other studies done by other institutions or organizations. Interval data cannot be multiplied or divided. Thus the difference between a person of 35 and a person 38 is the same as the difference between people who are 12 and Ordinal Data Ordinal data is usually data that can be ranked and put in place depending on the values that each subject has for example a football league table, the team with more points will be placed higher up in the league table.

Once we have the data in numerical form, we can manipulate it numerically. This is often used in psychological experiments that measure attributes along an arbitrary scale between two extremes. Those approaches included ethnography, phenomenology, narrative research, grounded theory, and case studies.

Notice that all of these scales are mutually exclusive no overlap and none of them have any numerical significance. This is often used in psychological experiments that measure attributes along an arbitrary scale between two extremes. Those approaches included ethnography, phenomenology, narrative research, grounded theory, and case studies.

Types of Qualitative Data This module will provide an overview of the most common types of data collection methods used in qualitative research studies.

It also includes an assessment of the advantages and disadvantages of each method. There are two major types of empirical research design: qualitative research and quantitative research. Primary data is data collected specifically for the research, such as through interviews or questionnaires.

Secondary data is data that already exists, such as census data, which can be re-used for the research. It is good ethical. In some areas of social research, the qualitative-quantitative distinction has led to protracted arguments with the proponents of each arguing the superiority of their kind of data over the other.

The quantitative types argue that their data is 'hard', 'rigorous', 'credible', and 'scientific'. The process of de-identification, by which identifiers are removed from the health information, mitigates privacy risks to individuals and thereby supports the secondary use of data for comparative effectiveness studies, policy assessment, life sciences research, and other endeavors.

The 4 types of research data policy are provided in full below. These policy texts are templates and journals may make minor changes to fit with.

In this Hub I will cover some of the basic understandings of research data, specifically targeted towards sports. Each of the sections can also be used for research of all types. Types of Data There are two different types of data that we use.
