Data collection services are always in demand by businesses. A business might need to research the market for a new product, enhance customer satisfaction, plan a marketing campaign, or expand its services. All you need is a market research agency to make a proper decision and proceed carefully.
Data collection methods are of two types – qualitative data collection and quantitative data collection. Today, we will talk about various quantitative data collection services.

What is the difference between qualitative and quantitative data collection methods?

The difference between quantitative and qualitative data collection methods is – you can measure quantitative data in terms of numerical data. You can conduct it through surveys, questionnaires, polls, and others.
Qualitative data is different in the sense that it is subjective. A market research agency can opt for this method if it wants to learn about the behaviours and responses of people affected by some event or cause. Researchers mostly use interviews through surveys and questionnaires to gather data.
Qualitative data may help you know why a person behaves the way he does, but the quantitative method will help you form objective conclusions. It depends on what you want to get out of your research.

Methods of Quantitative Data Collection

The interview is one of the oldest methods of quantitative data collection. Unlike qualitative data collection, where the interviewer can conduct an unstructured interview by asking open-end questions, interviews for quantitative data collection method is a structured. The interviewer will not ask anything outside the specified set of questions.

● Survey

The survey is an easy and common method of data collection. In qualitative data collection, a respondent can share whatever he wants or how much she wants to write. However, in the quantitative method, participants either have to tick the options or write a one-word answer. A market research agency can use this method to collect information about age, hobbies, jobs, and gender.
Another type of survey method includes marking on a scale. For example, you may get a form where you have to mark whether you strongly agree, agree, neutral, disagree, or strongly disagree. It can be through mail or offline.

● Observation
