Frage 4

A gardener counts 12, 15, 9, 14 and 15 tomatoes on five plants. Which statements about the mean of this data set are true? Select all that apply.

The mean is 15 tomatoes, because 15 occurs most often.
The five values total 65.Richtige Antwort
The mean is found by dividing 65 by 4.
The mean is 13 tomatoes.Richtige Antwort
The mean is 14 tomatoes, the central value once the counts are ordered.

Erklärung

The five counts add to 12 + 15 + 9 + 14 + 15 = 65, and dividing that total by the 5 plants gives a mean of 13 tomatoes. The count 15 occurs most often and 14 sits centrally once the counts are ordered, so each of those describes the data in a different way, and neither shares the total equally across all five plants.
