Detailed explanation-1: -For instance, consider the height of a student. The height can’t take any values.
Detailed explanation-2: -Quantitative data is numerical. It’s used to define information that can be counted. Some examples of quantitative data include distance, speed, height, length and weight.
Detailed explanation-3: -Examples of continuous variables are body mass, height, blood pressure and cholesterol. A discrete quantitative variable is one that can only take specific numeric values (rather than any value in an interval), but those numeric values have a clear quantitative interpretation.
Detailed explanation-4: -Height, weight, temperature and length are all examples of continuous data. Some continuous data will change over time; the weight of a baby in its first year or the temperature in a room throughout the day.
Detailed explanation-5: -Continuous data is a type of numerical data that refers to the unspecified number of possible measurements between two realistic points. These numbers are not always clean and tidy like those in discrete data, as they’re usually collected from precise measurements.
