Sampling Methods — Quiz

Question 1 • Grade 7 Mathematics

Perry performs a study to determine the average number of flowers on gardenia bushes at a plant nursery. Which will produce the most representative results?

Answer
A
a sample of 10 gardenia bushes in the shade and 10 in full sun
B
a sample of every other gardenia bush in full sun
C
a sample of the first 20 gardenia bushes near the entrance
D
a sample of every other gardenia bush in the shade

Explanation

A representative sample should include gardenia bushes growing under different conditions, since shade and full sun could affect how many flowers they have. Choice A samples 10 bushes from each condition, so it includes both groups rather than measuring only one area or growing condition. The other choices sample only bushes in shade, only bushes in full sun, or only bushes near the entrance.
