d. What type of data is provided by the information that Facebook is a social networking website

Short Answer

Expert verified

A) First Column : Quantitative Ordinal Variable ; B) Second Column : Qualitative Categorical ; C) Third Column : Quantitative Continuous Variable ;

Step by step solution

01

Basics 

  • Quantitative variables can be measured in terms of numerical units.

Ordinal variables are in form of ranks - 1st, 2nd, 3rd & so on

Continuous variable can be in form of whole & non whole numbers - can take values like 4.8, 10.5 etc

  • Qualitative variables can't be measured in terms of numerical units.

Categorical variables can take only few options or categories, like gender 'male' or 'female'

02

Explanation 

1st column depicts respective ranks of companies, it is Quantitative Ordinal Variable

2nd column depicts names of companies, it is Qualitative Categorical Variable

3rd column depicts IPO amounts - also in decimal values, it is Quantitative Continuous Variable

Facebook is a social networking site denotes category of website (social networking), it is Qualitative Categorical Variable
