Question
Which of the samples shows more variation?
Sample 172,75,83,88,92,96,101,107,109,115,115,126,130
Sample 2
89,89,90,92,94,107,108,109,110,112,121
Answer:
I think is sample 1. But I wonder which is the best calculation I should use to answer?
I calculated,
Mean
Sample 1 Sample 2
102.2 101.9
MAD
Sample 1 Sample 2
15.5 10.1
IQR
Sample 1 Sample 2
27 20
Range
Sample 1 Sample 2
58 32
I think sample 1 has more variation because the data points are more spread. Is this correct? Thanks
