Question

a teacher asked her students how many pets they own. here are the results: 0,0,1,1,1,1,1,2,2,2,4,4,8. on a piece of paper, draw a dot - plot to represent the data. then determine which answer choice matches the dot - plot you drew.

Explanation:

Step1: Count frequency of each value

0 appears 2 times, 1 appears 5 times, 2 appears 3 times, 4 appears 2 times, 8 appears 1 time.

Step2: Analyze option A

In option A, the frequencies match our counts: 2 dots above 0, 5 dots above 1, 3 dots above 2, 2 dots above 4, 1 dot above 8.

Step3: Analyze option B

In option B, there are extra dots at some positions and wrong frequencies, so it is incorrect.

Step4: Analyze option C

In option C, the frequencies at some values do not match our counts, so it is incorrect.

Step5: Analyze option D

In option D, the frequencies at some values do not match our counts, so it is incorrect.

Answer:

A.
