You can collect quantitative data in many different ways. Let’s have a look at a few of them.
1. Probability Sampling
Probability sampling is a great way to eliminate sampling bias. It allows you to reach out to your target population and collect data in the most effective way possible with a representative sample.
Additionally, you can opt for any of the following sampling techniques as per your convenience and requirement.
Simple random sampling – In this, each member of the targeted population has an equal probability of being selected for sampling.
Systematic random sampling – In this, each member of the population is selected from a preset or ordered sampling frame. For example, you select the first target member for sampling randomly and then select the rest in a predetermined fashion thereafter, say every third member of the group or say, every fifth member of the population.
Stratified random sampling -In this method, you divide the population into smaller sub-groups called strata. These strata are made using a common attribute that defines that set of people, for example, income or occupation.
2. Questionnaires and Surveys
This is a great way to collect quantitative data as it involves quick and to-the-point questions and answers. It comprises surveys, checklists, and ratings. You must have often come across surveys asking you about how many times you buy a certain product or service. These surveys are commonly used to understand customer value and monitor their dependency on the product or service.
Web-based questionnaires often come in the form of a survey link in your mail and include some close-ended questions that aim to collect information about a specific topic. These surveys can be created using secure online survey tools that are easy to collect and can be accessed anywhere and anytime.
