Question

look at these dot plots. which statement is true about the two data sets? both have the same mode. both have a gap between 28 and 31. both have the same range both have the same number of data points.

Explanation:

Step1: Define mode

Mode is the most - frequently occurring value. Visually, it's the value with the most dots. The modes for the two data - sets are different.

Step2: Check for gaps

In the "Highlands" data - set, there are no dots between 28 and 31. In the "Lowlands" data - set, there are no dots between 28 and 31. So, both data - sets have a gap between 28 and 31.

Step3: Define range

Range = Maximum value - Minimum value. The maximum and minimum values for the two data - sets are different, so the ranges are different.

Step4: Count data points

Counting the dots in each data - set shows that the number of data points is different.

Answer:

Both have a gap between 28 and 31.
