(2) SPREAD:
IQR (Interquartile range)= upper quartile - lower quartile
IQR of Back - IQR of Forward
I notice that the middle 50% of the weights for each of the sample distributions have a slightly higher/significantly higher /similar spread.
This means that there is only a small/huge/no difference between the median weight for this sample. The IQR for the forward sample is 12.5 m and the IQR for the back sample is 8kg
.
(3) SHIFT/OVERLAP:
I notice that there is significant/slightly/ does not overlap between the forward and back middle 50% of weights in this sample distribution. The LQ, median, UQ of the forward sample is only slightly higher than the female sample.
This indicates that there is not much/ huge difference between the weight of forward and back students in this sample.
