Then I would calculate the percentage of change of these expenses over a long enough period to smooth seasonal fluctuations and display them on a line graph, which is easy to interpret. The slope of the line of the office supplies compared to similar items consumed in the department would show whether my boss' assertion was true or not.
3. I would display the data in the form of a standard bell curve. This would reveal the average reading level of the students, which would be an appropriate target for a curriculum if all other things were equal. However, this type of distribution display would also show if there other factors to take into account, such as a significant number of "outlier" scores, or skewness, or large standard deviations.
4. Though the city council asked for the average, averages can be severely influenced by unusually low or high scores, so I would also give them the mode, because by knowing the most frequent score, they would know at what income level the largest number of people would be affected by any social program with income qualifications or cut-off points that the city council might consider.
6. I would compile minimum funding level requests/requirements for all the agencies the organization supports, then compare those levels to the funding granted by the organization.
