Find the mean, median, range, interquartile range, and mean absolute deviation of the data set:8, 9, 10, 10, 10, 11, 11, 11, 12, 13
+118724 They are already in order so the median is the middle one (or average ofthe middle 2)
8, 9, 10, 10, 10, 11, 11, 11, 12, 13
Median = (10+11)/2 = 10.5
Interquartile range = 11-10 = 1
range = highest score -lowest score
Mean is the average add them all up and divide by haow many numbers that there are.
Here is a video you can watch about the mean absolute deviation.
