Question

roger is training for the upcoming track season and records the number of miles that he runs each day for 20 days: 2.5, 0.5, 1.5, 5, 2, 2.5, 0.5, 4, 4.5, 3, 1.5, 1, 0.5, 2.5, 3, 0.5, 4, 4.5, 2, 4. which dot - plot displays the data correctly? rogers training 0.5 1 1.5 2 2.5 3 3.5 4 4.5 5 miles run rogers training 0 25 4 1.5 2 3 4.5 1 5 3.5 miles run rogers training 0 1 1.5 2 2.5 3 4 4.5 5 miles run

Explanation:

Step1: Count data - point frequencies

Count how many times each value appears in the data set: 2.5 appears 4 times, 0.5 appears 5 times, 1.5 appears 3 times, 5 appears 1 time, 2 appears 3 times, 4 appears 3 times, 4.5 appears 2 times, 3 appears 2 times, 1 appears 1 time.

Step2: Check dot - plot frequencies

Check each dot - plot to see if the number of dots above each value on the number line matches the frequencies calculated in Step 1.

Answer:

The first dot - plot displays the data correctly as it has the correct number of dots above each value on the number line corresponding to the frequencies in the data set.
