Find the mean, median, and mode of the data set. Round to the nearest tenth. 15, 13, 9, 9, 7, 1, 11, 10, 13, 1, 13

Question

mean = 8.5, median = 10, mode = 8
mean = 9.3, median = 10, mode = 13 mean = 8.5, median = 10, mode = 13 mean = 9.3, median = 8, mode =13

Answer 1

Look up your definitions.
Since 13 appears 3 times, the most times, 13 must be the mode
For the median, arrange them in order, pick the one in the middle
For the mean, just add them all up, then divide by 11

I am not going to do the arithmetic for you.

Answer 2

Mode = most frequently occurring score, 13

Median = arrange in order of value and choose the middle-most score.

Mean = Add the values of the scores and divide by the number of scores.
