which of the following is the correct dot plot for the following data? 62, 60, 60, 62, 62, 64, 66, 58, 52…

Explanation:

Step1: Count data - point frequencies

Count the number of times each value appears in the data - set: 52 (1 time), 55 (3 times), 58 (3 times), 60 (7 times), 62 (9 times), 64 (3 times), 66 (2 times).

Step2: Analyze dot - plot a

In dot - plot a, the frequencies for the values match our counts. For example, there is 1 dot above 52, 3 dots above 55, 3 dots above 58, 7 dots above 60, 9 dots above 62, 3 dots above 64 and 2 dots above 66.

Step3: Analyze dot - plot b

Dot - plot b has incorrect x - axis values (ranging from 20 to 100 instead of 50 - 80 relevant to our data) and incorrect frequencies for the values in our data - set.

Step4: Analyze dot - plot c

Dot - plot c has incorrect frequencies for the values in our data - set. For example, the number of dots above 60 and 62 do not match our calculated frequencies.

Answer:

A. The dot - plot labeled 'a'
