### High School Mathematics - 211.1 Mean of The Ungrouped Data

 Ungrouped Data (Raw Data): A data set consisting of the observations for some variable is referred to as raw data or ungrouped data. The statistical mean is commonly called the average. To find the mean of a group of numbers: Add the numbers together Divide by how many numbers were added together Example: Find the mean of 3, 6, 11, and 8. Add all the numbers, and divide by the number of numbers in the list, which is 4. (3 + 6 + 11 + 8)/ 4 = 7 Therefore, the mean of these four numbers is 7. Example: Find the mean of 11, 11, 4, 10, 11, 7, and 8 to the nearest hundredth. (11 + 11 + 4 + 10 + 11 + 7 + 8) / 7 = 8.857Å The mean of the set of numbers rounded to the nearest hundredth is 8.86.
