Concept explainers
Interpretation:
Difference between qualitative data and quantitative data needs to be explained with examples.
Concept introduction:
Data is the collection of information obtained through observations about a person or a thing. Qualitative data is used for approximates and characterization. Quantitative data has numbers.

Answer to Problem 39A
Qualitative data is represented in names, symbols whereas quantitative data is represented in numeric values.
Explanation of Solution
Qualitative data is the measure of types and is mostly represented in the form of name, symbols or number codes. Whereas quantitative data is the measure of values or counts and is expressed in numbers. These are numeric variables representing the quantities as how many, how much or how often.
Element copper has the atomic symbol Cu, color red is the qualitative data whereas its
Planet Earth is round is the qualitative data whereas the mass of the earth
Qualitative data is the measure of type while quantitative data is the measure of value.
