Use the image to answer the question.

Two number lines extend from 41 to 50 in increments of 1 and are labeled as Dataset A and Dataset B. The number lines show an abacus-like representation with columns of open circles over the numbers. Above the number line labeled Dataset A, there are four circles over 41, five circles over 42, seven circles over 43, four circles over 44, two circles over 45, one circle over 46, one circle over 47, three circles over 48, two circles over 49, and one circle over 50. Above the number line labeled Dataset B, there is one circle over 41, three circles over 42, three circles over 43, five circles over 44, four circles over 45, six circles over 46, seven circles over 47, four circles over 48, two circles over 49, and one circle over 50.

Two datasets of numbers from 41 to 50 are displayed in two dot plots. Compare the shapes and spreads of the dot plots. What conclusions can you draw about the shapes and the spreads?
