Analysis:

1. CENTRE:

• I notice that the median weight of the sample is slightly higher/significantly higher /similar than the back sample median.

• This means that there is only a small/huge/no difference between the median weight for this sample. 

• The median weight for the forward is 110.5 which is only 18.5 higher than the back weight median of 92.

(2) SPREAD:

IQR (Interquartile range)= upper quartile - lower quartile

IQR of Male-            IQR Female-

• I notice that the middle 50% of the weight 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 kg and the IQR for the back sample is 8 kg.

.

(3) SHIFT/OVERLAP:

• I notice that there is significant/slightly/ does not overlap between the forward and back middle 50% of  weight in this sample distribution. The LQ, median, UQ of the forward sample is only slightly higher than the back sample.

• This indicates that there is not much/ huge difference between the median of the forward and back students in this sample.

• The forward sample LQ has shifted 104.5 kg up the scale, the median has shifted up the scale and the UQ has shifted 18.5 up the scale.
