The two dot plots below compare the forearm lengths of two groups of schoolchildren:
@Michele_Laino
Based on visual inspection of the dot plots, which group appears to have the longer average forearm length? Group A, because three children in the group have the least forearm length of 9 inches Group B, because three children in the group have the least forearm length of 9 inches Group A, because two children have a forearm length longer than 10 inches Group B, because seven children have a forearm length longer than 10 inches
hint: for group B there are more people than group A, whose forearm lengths are 11 and 12 inches
Group B then @Michele_Laino
I think option D, because in group B there are more people than group A who have high values for forearm lengths
OK thank you!! :)
