Document Summary

0 y c n e u q e r. > = 8 e u n e v e. I my opinion figure 4. 3 best represents the monthly revenue when choosing a histogram. Figure 4. 3 allows me to easily see how the data is distributed and skewed slightly to the left (-0. 15). Although figure 4. 2 shows that data is skewed to the left as well it doesn t fully express the shape of the distribution like figure 4. 3 does. Figure 4. 3 look skewed to the left, figure 4. 1 makes the data look symmetric which is not true. Looking at the boxplot, the mean (. 71) is slightly off from the median (). Had the two values been the same the chart would have been symmetric. However the mean is not equal to the median therefore both the boxplot and the histogram agree that the data is skewed left. The boxplot shows outliers better than the histogram.
