Type of beverage sold is a categorical variable because the values of the variable can only be placed into categories.

Explanation / Answer

Question 1:

What type of beverage sold is a categorical variables, because here the categories dont really have a numerical meaning and there is no ordinal behaviour in the variable as well which means we cannot say that tea is greater than coffee or something like that.

D is the correct answer here

Question 2:

Due to same reason as in above case though there is an ordinal behavior to it we cannot say how much smaller is small than medium and so on. Therefore again due to the same reasons as in previous part

D is the correct answer here

Question 3:

Time is a continuous variable because it is numerical also time can take any number of infinite values between 2 continuous variable values.

C is the correct answer here as Time comes from measuring process.

Question 4:

Here test score is a continuous variable but due to rounding off for example a score of 90.4 will be rounded to 90 and a score of 90.2 will be rounded to 90 also. Therefore although it is a continuous variable, the 2 students might have got exactly same marks due to rounding behavior

Therefore a is the correct answer here.
