Calculate the mean, median, and mode of the following set of data. round to the nearest tenth. 11, 9, 7, 6, 8, 2, 15, 1, 12, 15, 14mean: 11 + 9 + 7 + 6 + 8 + 2 + 15 + 1 + 12 + 15 + 14 = 100; 100/11 = 9.1 median: 9; 1, 2, 6, 7, 8, 9, 11, 12, 14, 15, 15; mode: 15 (appears most often.

Median is the middle most number, so you order from least to greatest. :)
11, 9, 7, 6, 8, 2, 15, 1, 12, 15, 14 which becomes: 1, 2, 6, 7, 8, 9, 11,12, 14,15,15.. So 1,2,6, 7, 8 can be grouped into the first upper section. 9 is the median since it's the middle because 11,12,14,15,15.

Mean is adding all values up and dividing by the total number you have. So you kind of did that, soo 100/11 = 9.1.

The mode is what is repeated the most, so, 15 appears the most (twice in total I believe). You already had the answers, but I hope this was enlightening ^^
