Using the score distribution: 89, 88, 86, 86, 84, 83, 83, 80, 75, 75, 75, 70, 86, 83, 84, which of the following best describes the score distribution?

Answer :

Answer:

C. Trimodal

Step-by-step explanation:

The mode of a data set is the value that appears most frequently.

If we list the given data set in increasing order, we get:

70, 75, 75, 75, 80, 83, 83, 83, 84, 84, 86, 86, 86, 88, 89

We can see that there are 3 values (75, 83, 86) that all have equally high levels of frequency. Therefore, this data set is trimodal, since tri- is the Latin root for 3.
