As a social science, sociology is an incredibly rich discipline. While a lot of that comes from the theoretical perspectives which lay the foundations for the subject, we can attribute a lot of the abundance of empirical sociological knowledge to the researchers who collect and analyse data.
Let's dive in!
Researchers collect, analyse and interpret primary and secondary data. Researchers themselves collect primary data, and secondary data is the use of someone else's outputs.
You can choose to use a questionnaire that will collect both quantitative and qualitative data, i.e., questions with numerical answers (respondent's income, for example) and qualitative answers (ask them to describe their socioeconomic status in their own words, for example). You could also ask the same questions during an interview - it is a matter of choosing which method will produce data most suitable for analysis and interpretation.
The figure below shows that both primary and secondary data can be quantitative and qualitative.
Fig. 1 - There are many different types of data
Primary research involves generating data that has not previously been collected or analysed.
If you wanted to find out whether 17-year-olds prefer either pizza or ice cream, you could go ask your friends who are 17 years old. That would constitute collecting primary data.
Examples of primary research methods in sociology (i.e., that yield primary data) include:
Questionnaires
Polls
Focus groups
As is the case with all sociological data and their collection methods, there are a number of advantages and disadvantages when it comes to using primary data.
Advantages of primary data | Disadvantages of primary data |

Table 1 - Advantages and Disadvantages of primary data.
Secondary research involves collating and analysing data that has already been generated.
Similarly, if you wanted to find out whether 17-year-olds prefer either pizza or ice cream, you could go online and look for statistics about the food preferences of adolescents.
Examples of secondary data sources include:
Archives
Research paper depositories
Photo and video material
Personal diaries/journals
There are also a number of strengths and limitations to be aware of when it comes to using secondary data in sociological research.

Tertiary data is not as commonly discussed when it comes to sociological research, but it can be quite important to take note of in certain types of research. Tertiary data include reference materials that have collected and regurgitated other data or information.
Examples of tertiary data sources include:
Textbooks
Manuals
Handbooks
Bibliographies
Guidebooks
Dictionaries
Encyclopedias
While primary, secondary and tertiary data come from various sources and have various uses, the many types of data themselves also have some notable differences. For instance, data can either be quantitative or qualitative. Let's explore what this means.
Sociological researchers use different forms of data depending on their topic and research objectives. For instance, they may want to consider whether the aim of their research is to measure something numerically or to describe and/or analyse it in detail. This is where sociologists have to decide whether they are seeking quantitative or qualitative data.
Quantitative data is used to measure social phenomena in numerical, statistical or analytical terms. For example, you could measure the height of your classmates in numerical terms (e.g. 162 cm or 175 cm)
Qualitative data is used to describe phenomena examined in categorical terms. Using the same example, you could ask your classmates to describe each other using categories “short”, “medium height” and “tall”.
As we have seen in the example above, quantitative data takes a numerical (or 'number') form.
A sociologist might opt for methods which generate quantitative research if they want to examine social patterns or if they'd like to study the nature and/or strength of a relationship between two or more factors. There are various types of quantitative data, which you will learn more about later on in your academic career. In the meantime, we can take a look at some examples:
On the other hand, qualitative data is data that is not in numerical form (but is also not necessarily just 'words').
A sociologist might prefer qualitative data if they are looking for an in-depth description and/or analysis of aspects of social life. Types of qualitative data include:
Descriptions of observations
Interview transcripts
Written sources (such as diaries, journals, novels, newspaper articles, etc)
Visual media (including photographs, paintings and videos)
Audio media (such as recorded music)
Some concepts need to be expressed in a way that makes them measurable - we have to operationalise them.
For instance, how might we measure the amount of 'exercise' that a person does? As a researcher, you will likely use indicators or proxy measures, which are typically expressed as quantitative data. For example, you could examine hours of exercise completed by using gym attendance rates, or you could conduct standardised fitness tests at various points and study the difference in results over time.
Some researchers prefer to combine quantitative and qualitative research methods in pursuit of a fuller picture of social phenomena. There are two different approaches that researchers can take here:
Triangulation allows researchers to check whether data collected is valid and reliable by collecting it from two or more different sources. By seeing the same thing from different perspectives, the researcher confirms or challenges their findings of one method through the use of another.
On the other hand, a researcher may adopt a variety of sources due to believing that no single research approach is superior to another. This is methodological pluralism, or a mixed methods approach.
You may choose to observe your participants and then select a purposive sample to conduct questionnaires. This would allow searching for patterns using quantitative data, and unstructured interviews - for context and depth.

Now that we know what questions sociologists ask when it comes to the type and form of the data they are seeking, another important question to ask is the qualities that they want this data to have. Some of the most commonly sought qualities of scientific data are validity and reliability.
Data is considered to be valid if it accurately presents a particular description, measurement or finding.
For example, many sociologists suggest that Official Statistics on crime are not quite valid, because many crimes (such as white-collar crimes) go unreported. As such, the statistics do not paint an accurate picture of the prevalence of crime.
Data is considered to be reliable when, if other researchers were to use the same methods, they would obtain the same results.
For example, a researcher might observe the behaviour of sports fans at a football match in the UK. If another researcher observed the same crowd at the same event, and their results matched those of the first researcher, this data would be considered reliable.
Researchers can collect data themselves or use data collected by someone else. That is the distinction between primary and secondary data. Both data collection methods have advantages and disadvantages.
Data can also be quantitative (i.e., numerical, statistical) or qualitative (i.e., descriptive, categorical).
Some concepts in sociological research are abstract and need to be operationalised in order to be measured.
Some researchers prefer to use mixed methods. The belief that no single research approach is superior to another is called 'methodological pluralism'.
Triangulation is a mixed-methods technique used to validate the data by collecting it through various research instruments. Furthermore,

What is data in sociology?
In sociology, the term 'data' is used to refer to any form of information which tells us about the social world. This includes a variety of phenomena, such as behaviour, systems, and institutions.
What are data collection methods in sociology?
Many data collection methods are well suited to generate sociological data. Perhaps the most common data collection methods used in sociology are interviews, surveys, ethnographic studies and secondary data analysis.
What are examples of secondary data?
Examples of secondary data sources include documents, Official Statistics, photo and video material, personal diaries, and many more!
What sociologists use secondary data?
There are countless uses for secondary data in sociology. This method of research cuts costs and time, and allows new perspectives to be applied to existing information.
What is an example of tertiary data?
Tertiary data is not as commonly discussed when it comes to sociological research. It includes reference materials that have collected and regurgitated other data or information. Some examples of tertiary data are textbooks, handbooks and dictionaries.
