Question

PLZ HALP!!!!!

The number in the chart are the math test scores of 10 seventh hrade students.



Which of the following is most affected by the lower score?

A.) the mean and median
B.) the median
C.) the mean
D.) the mode​

Answer 1

The mean... the median is in the middle, it won't change, the mode is the most repetitive number and it won't change neither... so the mean will be the most affected.

Answer 2

C

Explanation:

The mean of a set of values is the average of all of them. The median is just the center most value when you arrange the values in order from least to greatest, or the average of the most central two if there is an even number of values. The mode is simply the value that shows up the most. The single, low outlier does not affect the median and mode almost at all, and only has a large influence on the mean, since it brings down the average. Therefore, the correct answer is choice C. Hope this helps!
