A. The mean will increase.
To find the mean, we sum up all the measurements and divide by the total number of measurements.
Mean = (3.7 + 2.5 + 2.3 + 1.2 + 3.4 + 2.3 + 3.2) / 7 = 18.6 / 7 = 2.657 inches
Now, when we add the two new measurements, the sum will increase, which will cause the mean to increase as well.
The following measurements show the lengths of 5 grasshoppers in inches:
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
