discuss how to interpret the mean, median, and standard deviation of a data set.

Answer #1

Mean represents an average value of the inputs of a data set. The mean can simply be found out by dividing the sum of the data points by the number of data points.

Median represents the central value of the data set. It can be found by simply arranging the data points in ascending order and if there are odd data points then the central value is the median and if there are even data points, then the average of the two central points is the median.

Standard deviation is a measure of the spread of a data set. It highlights how far on average the data points are to each other. It is measured by finding the square root of variance.
