Question

What are different types of statistical data? Which
one is more reliable?​

Answer 1

Answer:

Types of Statistical Data:

Information on any field, when expressed qualitatively and/or quantitatively, is called data and they are usually classified into two main cate­gories—primary and secondary data, depending on their origin or source.

Information when collec­ted directly from the desired field for the use of a predetermined purpose is called the primary data e.g., heights and weights of the students in a class.
