To find the average, add the scores and divide the sum by how many scores you are adding: 81 + 76 + 91 + 73 + 79 = 400 ÷ 5 = 80.

To calculate the mean, add all the numbers (76 + 82 + 73 + 93 + 91 + 81 + 79 + 86 + 84 = 765) and divide by the total count (9), resulting in a mean of 85. The median, when the numbers are arranged in order (73, 76, 79, 81, 82, 84, 86, 91, 93), is 82. The mode does not exist as all numbers appear only once. The range is 93 - 73 = 20, and the standard deviation is approximately 6.07.
61 + 73 + 71 + 80 + 87 + 90 + 90 + 90 + 87 + 83 + 73 + 63 = 948 / 12 = 79 The average of the numbers is therefore 79.
76 years. The number of years it is from 1879 to 1955 is represented by the expression 1955 - 1879, which equals 76 years.
They could come from a table of integers. They are certainly not from any multiplication table (other than for 1).
