In order to collect quantitative data, the first step includes the need to develop the operational definitions of the abstract concept you wish to study. For instance, if you wish to study the emotions (an abstract concept) that your product is eliciting in the consumers, you can make this variable observable by quantifying it (e.g. self-report of the feelings consumers have when using the product in question).
Thus, the operational definition of the concept under study usually helps in providing you with a direction in which you can study your area of interest.
Since quantitative research relies on objectivity, elaboration, and sometimes is also investigational, the data collection is usually done by employing structured methods. These methods are conducted on larger samples. These samples usually represent the population of interest in the study on which the results will be generalized.
There are two methods through which you can conduct quantitative research, they are
- Primary Quantitative Research Methods
- Secondary Quantitative Research Methods
Let’s go over each one of them in detail in the following sections.
01. Primary Quantitative Research Methods
This research method is most widely employed for conducting market research. Here, the researcher directly collects data from the sample rather than depending on the data that has been collected from previous research.
In this section, we will understand the types of quantitative designs, the several ways to collect data from primary sources, and data analysis under quantitative.
Types of Quantitative Designs
Primary quantitative research can be conducted in various ways, four of which are described below:
- Survey Research
- Correlational Research
- Quasi-Experimental Research, or Comparative Studies
- Experimental Research
1. Survey Research
Survey research is the most common and widely used approach for quantitative research. Surveys are used to gather data by asking relevant questions to the respondents who are thought to have the relevant information we are seeking to acquire.
Generally, a formal list of questionnaires is prepared which is circulated to the respondents and they can self-report their thoughts. Researchers use a non-disguised approach so that the survey participants know exactly what they are answering. The respondents are asked basic questions such as their demographic details, and the topic of interest.
Surveys can be conducted through online polls, paper-pencil questionnaires, web-intercept surveys, etc. Big and small organizations conduct surveys when they want to understand the opinions/feedback of their customers about their products and services.
Surveys are important because they give organizations an opportunity to ask multiple questions, collect data from a large number of customers and analyze the collected data. The biggest advantage of survey research is that researchers can choose a specific target audience group or can conduct the survey across multiple groups for comparative analysis.
Researchers need to, however, make sure to sample the respondents for the survey randomly. This is one way of ensuring that the research conducted is fair and unbiased, and every respondent irrespective of their beliefs and opinions has a fair chance of being a part of the survey.
There are two kinds of surveys and researchers generally choose the type that fits their time at hand and the kind of data they want to analyze.
In cross-sectional surveys, the study takes place at a single point in time. Hence, cross-sectional surveys do not entail the manipulation of the variables under study and are limited in that way.
Cross-sectional surveys allow researchers to study various characteristics, such as the demographic structure of the consumers, their interests, and attitudes, all at once. It aims to provide information about the population at the current moment in time.
For example, cross-sectional surveys will tell us how the consumer is responding and feeling about the product at the present moment. It does not study the other variables that may affect the consumers’ reactions to the product in the future.
Longitudinal surveys, on the other hand, involve studying variables for a long period of time and observing the changes in them from time to time. Here, the data is collected from the respondents at the beginning of the study, and then the researcher collects data at different time intervals until the end of the study.
Longitudinal surveys are more popularly used in medicinal science to understand and evaluate the effects of medicines, or vaccines, in the long run on participants. Because longitudinal surveys take place for several years, researchers can establish the sequence of events that may affect the variable under study.
