Question

Mike, your buddy in QMB 2301, does not go to class often. Before the exam, he wants to study with you. You try to teach him the concept of quantitative and categorical data. He says: “Any categorical data can be converted to quantitative data by just assigning a number to it. Likewise, any numerical data can be converted to categorical data by just spelling out the words of the numbers.” Explain why Mike is wrong.

Answer 1

Mike is wrong, as there is a huge difference between categorical data and quantative data . And no categorical data can be converted into quantative data just assigning a number tp it, because categorical data is soomething that cannot be measured in numbers, and if we are assigning some numbers to the categorical data then it is just to make it ordinal the numbers actually doesn't have to do anything with the categorical data.

And we cannot convert numerical data to categorical data by just spelling out the words of the numbers because numerical data is something that is related to numbers and it is measurable .
