What is the outlier? 12 – Mrs. MacMillian’s class7. How does the outlier affect the mean? With the outlier the mean is 25.5 students per class. Without the outlier the mean is 28.2 students per class. The outlier decrease the average number of students per classLesson 6-4 Bar GraphsUnited Kingdom8.

It decreases 24. In which months does the city usually receive the same amount of precipitation? October and DecemberLesson 6-8 Misleading Graphs
10. 10. 26. Why is this graph misleading? The graph is misleading because scale on the y-axis does not start at zero – it starts at 40. The lower part of the vertical scale ismissing, so the differences in attendance seem greater than they really are.27. What might people believe from the misleading graph? It looks like from Mayto June the baseball attendance dropped drastically almost to nothing. Peoplemight believe that no one attended baseball in June. The actual decrease wasfrom 83,000 to 41,000.
