Question

When a percentage of the smallest and largest values are deleted from a data set, the mean of the remaining data values is the a. geometric mean. b. weighted mean. c. trimmed mean. d. interquartile mean.

Answer 1

Correct option C

Trimmed mean

Step-by-step explanation:

A trimmed mean is a method of averaging that removes a small designated percentage of the largest and smallest values before calculating the mean.

Trimmed mean helps eliminate the influence of data points on the tails that may unfairly affect the traditional mean.

Trimmed means are used in reporting economic data in order to smooth the results and paint a more realistic picture.
