The following measurements show the lengths of 5 grasshoppers in inches:

Question

3.7, 2.5, 2.3, 1.2, and 3.4

What will happen if 2 more grasshoppers with measurements of 2.3 and 3.2 inches are added?
A.
the mean will increase

B.
the median will increase

C.
the mean will decrease

D.
the median will decrease

Answer 1

The correct answer is B. the median will increase.

The median is the middle value when the data is arranged in order. In this case, the median is 2.5 inches.

When two grasshoppers with measurements of 2.3 and 3.2 inches are added, the new data set would look like this:

1.2, 2.3, 2.3, 2.5, 3.2, 3.4

Now, the median would be 2.5 inches. Since the median has increased, the correct answer is B. the median will increase.
