Do the data shown in the boxplot below have a greater amount

Do the data shown in the boxplot below have a greater amount of variability within levels A, B, C, and D or between the four levels? Explain. The boxplot shows The boxplot shows greater variability within the four levels. The means for each are all quite similar. The boxplot shows greater variability between the four levels. The means for each are all quite different. The boxplot shows greater variability within the four levels. The means for each are all quite different. The boxplot shows greater variability between the four levels. The means for each are all quite similar.

Solution

Option 2

The boxplot shows the greater variability between four levels. The means for each are all quite different.

The means of levels A,B,C,D are different because the boxplot are not overlapping and the plot shows that

mean A < mean B < mean C < mean D.
