Question

the stemplot displays 26 students scores on a 90 - point statistics test. which of the following best describes the shape of the distribution of test scores? test scores 4|3 4|5 6 5|1 2 3 5|5 7 6|0 3 3 6|5 6 7 7 9 9 7|1 1 2 4 7|6 7 9 8|4 8|5 key: 6|8 = 68 points

Explanation:

Step1: Observe the stem - plot

Count the frequencies in each stem.

Step2: Analyze the shape

The lower scores (in the 40 - 50 range) have fewer data points, and the higher scores (in the 70 - 80 range) have more data points. The tail of the distribution extends towards the lower scores. This indicates a left - skewed distribution. Also, there is no clear indication of two modes (bimodal) and it is not symmetric.

Answer:

slightly skewed left
