the range is the highest score minus the lowest score, 100-60 = 40................... The median is the middle number which is 80 since there are 10 numbers before it and 10 numbers after it. The highest test score is clearly 100. The interquartile range is the difference of Q3 and Q1 which are the median of the upper half and the lower half, the edge of the box plot.... Q1 is 69, the median of the lower half. Q3 is 91, the median of the upper quartile. The IQR (Interquartile range) is 91-69 = 22
