Mean (17+7+11+13+2+12+7)÷7=9.86 median 2, 7, 7, 11, 12, 13, 17 (7+1)÷2 = 4th number so the median is 11 mode 7 (unimodal) range highest-lowest = 17-2= 15

First we arrange the raw data from least to greatest: 2,7,7,11,12,13,17

Next we find the mean. The mean is the average so just add and divide to the total number of raw data 2+7+7+11+12+13+17=69 69/7=9.86 Now we find the median or simply the middle which is 11. Lastly we find the mode. The mode is the value in the raw data that has the highest repetition. So the mode is 7 because there are 2 #7. Hope this helps =)
