Given the data set below, identify quartile 1, the median, quartile 3, and the interquartile range (IQR)
21, 22, 22, 25, 25, 36, 46, 61, 82, 86, 87
1. Quartile 1
2. Median
3. Quartile 3
4. IQR
a. 21
b. 22
c. 36
d. 60
e. 82
f. 87
1. Quartile 1: 22 (since it is the 3rd value when the data set is arranged in ascending order)
2. Median: 36 (since it is the middle value when the data set is arranged in ascending order)
3. Quartile 3: 82 (since it is the 8th value when the data set is arranged in ascending order)
4. IQR: 82 - 22 = 60
