Answer 1

Question 1: Nominal Scale (categorical variable scale) is a scale used for labelling variables into distinct classifications and doesn’t involve a quantitative value or order. Here we would like to categorise the political affiliation into different categories like Democratic, Republican, Independent etc, so we will use nominal scale here.

Answer: Nominal

Question 2:Since the students think that the exam was easy, so there is a high chance that they will score good marks in the test. And these high marks will result in a higher frequency to the right side of the distribution. This gives a negatively skewed distribution.

Answer: Negatively skewed
