The dot plot shows the weight, in grams, of several different rocks. Select all the terms that describe the shape of the distribution.

(A) Bell Shaped
(B) Bimodal
(C) Skewed
(D) Symmetric
(E) Uniform

Option B and D are the correct Answer.

Explanation:

A bimodal distribution with two very common data values seen in a dot plot or histogram as distinct peaks. In the dot plot shown, the two common data values are 0.27 and 0.31.

In the given data points, the mean = median,

so the distribution is also symmetric.

There are 33 terms, the median is the 17th term which is 0.29.

The mean is the sum of the observations/total number of observations =`\frac{ 9.58}{33}` = 0.29
