Question

Given the following students' test scores (95, 92, 90, 90, 83, 83, 83, 74, 60, and 50), identify the mean, median, mode, range, variance, and standard deviation for the sample

Answer 1

The mean is the average of a set of data, while the median is defined as the middle value of a set of data. For even values of a set, the median is the average between the two middle values. Mode is the value that appears the most times, while range is the span between the smallest and largest values. Standard deviation measures how far the set of values deviates from the average, while the variance is the square of the standard dev.

Mean = 80
Median = 83
Mode = 83
Range = 72.5
Standard Deviation = 13.9
Variance = 193.2
