<h3>What is a Qualitative and a Quantitative Data?</h3>
A quantitative data can be described as a type of data that you can measure or counted, and also given a numerical value to, while a qualitative data is a type of data that cannot be expressed using numbers.
Examples of quantitative data include, number of students in a class, weight of students in a class, etc.
Examples of qualitative data include hair color, religion, nationality, etc.
Expenses of respondents can be given numerical values, therefore, expenses of respondents in a survey is a quantitative data and the level of measurement is a ratio scale.
