SECTION 1: DATA TYPES AND LEVELS OF
MEASUREMENT (Questions 1-8)
Question 1
Is the statement below true or false? Continuous data are the type of
quantitative data that is the result of measuring.
A) True
B) False
Answer: A) True
Rationale: Continuous data is quantitative data that can take any value
within a range and is obtained through measurement. Examples include
height, weight, temperature, and time. Discrete data, by contrast, comes
from counting and can only take whole number values .

Question 2
A doctor notes her patient's temperature in degrees Fahrenheit every hour to
,make sure the patient does not get a fever. What is the level of
measurement of the data?
A) Nominal
B) Ordinal
C) Interval
D) Ratio
Answer: C) Interval
Rationale: Temperature in degrees Fahrenheit is interval data because it has
equal intervals between values but lacks a true zero point (0°F does not
mean the absence of temperature). The lack of a meaningful zero prevents
the calculation of ratios .

Question 3
An English professor asks her students who their favorite character is in the
novel they are reading. What is the level of measurement of the data?
A) Nominal
B) Ordinal
C) Interval
D) Ratio
Answer: A) Nominal
Rationale: Favorite character names are categories or labels without any
inherent order or numerical meaning. This makes them nominal data—the
lowest level of measurement. Nominal data consists of categories that
cannot be ordered or ranked .

Question 4
Academic major is what level of measurement?
, A) Nominal
B) Ordinal
C) Interval
D) Ratio
Answer: A) Nominal
Rationale: Academic majors (e.g., Biology, History, Mathematics) are
categories without any inherent order or numerical value. They represent
nominal data, which is purely categorical with no meaningful ranking .

Question 5
Number of calories consumed is what level of measurement?
A) Nominal
B) Ordinal
C) Interval
D) Ratio
Answer: D) Ratio
Rationale: Number of calories consumed is ratio data because it has equal
intervals, a true zero point (0 calories means none consumed), and
meaningful ratios (200 calories is twice as much as 100 calories). All
arithmetic operations are meaningful .
