2 true or false 10 points
the drink size of a soda, categorized as small, medium or large, would be considered a nominal scale (aka nominal level of measurement)
○ true
○ false

3 multiple choice 10 points
what level of measurement is used with a likert scale? (i.e., a scale with ranked categories of \strongly agree,\ \agree,\
eutral,\ \disagree,\ and \strongly disagree\
○ nominal
○ ordinal
○ interval/ratio
○ none of the above

Explanation:

Question 1

The nominal scale is the least precise level of measurement as it only involves categorizing data into distinct groups with no order or numerical value (e.g., gender, eye color). Ordinal has order, interval has equal intervals, and ratio has a true zero, all more precise than nominal.

Drink sizes (small, medium, large) have an order (ordinal scale), not just categories (nominal). Nominal is for unordered categories, so the statement is false.

A Likert Scale has ranked categories (strongly agree to strongly disagree), which is characteristic of the ordinal scale (order exists but no equal interval between categories). Nominal is unordered, interval/ratio has equal intervals, so ordinal is correct.

Answer:

A. nominal
