Answer 1

Answer:

Quantitative variables usually represent membership in groups or categories (False)

Bar and pie charts are graphical techniques for nominal data. The former focus the attention on the frequency of the occurrences of the categories, and the later emphasize the proportion of occurrences in each category (True) because bar charts are drawn to show frequency of occurrence and distribution, while pie charts are drawn to show emphasis on the proportions of occurrence in each category relative to 360 degrees.
