Data shows the number of seconds it took two randomly selected groups to thread a needle. Compare the measure of center and variability of these data sets.
Student group A:56,14,26,29,45,32,80,3,10
Student group B: 27,24,18,19,5,16,22,10,6,20
The range of the time by group A and group are the same.
Median time taken by group A to thread a endless higher than group B.
The mean time taken by group A is higher than that of group B
The amount of variability of the same taken by group A to thread a need is higher than the amount of the variability of the time taken by group B

This means that group A took longer, on average, to thread a needle than group B and had more variation in their times. Group B had a lower median and mean time taken and less variation in their times.
