Answer:
Median: 25
Upper quartile: 30
Lower quartile: 20
IQR: 10
Step-by-step explanation:
The nice thing here is they already put them in order :)
16, 18, 20, 22, 24, 26, 28, 30, 32, 34
For the median, it's the middle number of the ordered data set. Unfortunately here, there is an even number of entries. In that case, we average the middle two numbers, 24 and 26. 24 + 26 = 50/2 = 25
For lower quartile/Q1, you take the middle number of the bottom half of the data set. Bottom half: 16, 18, 20, 22, 24...so the middle is 20
For the upper quartile/Q3, you take the middle number of the top half of the data set. Upper half: 26, 28, 30, 32, 34...so the middle is 30
For interquartile range/IQR, you calculate the range from third to first quartile: 30-20 = 10
