Answer:
Range = 19-11 = 13
Median = (12+15)/2 = 13.5
Mean = 14.3
IQR = 5
Variance = 8.45
Standard deviation = 2.907
Explanation:
12 17 19 15 12 18 11 15 12 12
Arranging in ascending order
11 12 12 12 12 15 15 17 18 19
Range = 19-11 = 13
Median = (12+15)/2 = 13.5


Interquartile range

Interquartile range is 5
