The only point to keep in mind aside from the rules covered so far and reiterated in the list immediately above is this: the top of the bars in a bar graph should be even with the point on the y-axis equal to the value they represent. That is if the y-value being plotted is 10 then the top of the bar should be even with the mark on the y-axis that represents 10 (whether that mark is labeled or not). Your instructor may provide some introductory examples before having you complete the following exercise. A1. Prepare a histogram using the data at the bottom of the page: B. Preparation of Line (Scatter) Graphs: The Effect of Clutch Size on Nestling Survival The term clutch size is used to refer to the number of eggs in the nest of a mated pair of birds. The mean (average) number of eggs is characteristic of each particular species but as with all other characteristics (as you will see in unit 2 in lecture) there is some variati
