Example: 2, 3, 4, 5, 6.
Example: 2+3+4+5+6=20{\displaystyle 2+3+4+5+6=20}
Example: 2, 3, 4, 5, and 6 make for a total of five values.
Example: 20/5=4{\displaystyle 20/5=4}. Therefore, 4 is the mean of the numbers. You can check your calculations by multiplying the mean by the number of values in the set. In this case, multiply 4{\displaystyle 4} (the mean) by the 5{\displaystyle 5} (the number of values in the set) and your result will be 20{\displaystyle 20} (4∗5=20{\displaystyle 4*5=20}).
