Mean - The average of all the values in the data set is known as mean. Since 100 is an even number, we need to find the mean of the middle two data values - the 50th and 51st data values. 3. These values (5 and 5.56) are called, respectively, the population variance and the sample variance for section D. We are almost thereone more step, and we will find the standard deviation. Another common measure of variability is known as standard deviation, which measures how far each one of the measurements is from the mean. The mean is the value that keeps the data in balance, like in the picture below. To calculate the median first, list the numbers in order. For section B, the range is 10 since 10 0 = 10.
