Solution

The difference between mean and standard deviation:
Mean Standard Deviation
Mean is the ratio of the sum of all values to the total number of values. The standard deviation is the measure of the dispersion of the data values from the mean.
Mean is used to measure the average. Standard deviation is used to measure volatility.
Hence,mean denotes the average and standard deviation denotes the variation in data
