To find the mean, we add up all of the scores and divide by the total number of scores:
5.1 + 5.6 + 5.3 + 5.1 + 4.8 + 4.6 + 5.2 = 36.7
36.7/7 = 5.242857...
Rounding to the nearest tenth, the mean is 5.2.
To find the median, we need to put the scores in order from least to greatest:
4.6, 4.8, 5.1, 5.1, 5.2, 5.3, 5.6
The median is the middle number, which is 5.1 in this case (since there are an odd number of scores).
At a middle school gymnastics competition, the scores for the floor exercises were 5.1, 5.6, 5.3, 5.1, 4.8, 4.6, and 5.2. Find the mean (to the nearest tenth) and the median.
