2. Never attempt to interpret the results of a statistical procedure you don't fully understand. If you need to interpret a particular statistic, talk with a professional statistician and make sure you understand the proper interpretation. Unlike descriptive statistics, inferential statistics is anything but black and white, there may be several valid interpretations of a given statistic, and you need to be aware of which ones are better under which circumstances.
The pie chart below shows descriptive statistics on health issue within a population. It illustrates that the employees who attended the training program were less likely to be absent from work due to sickness. This suggests that the staff training program is effective in combatting upper limb injuries. Assuming that upper limb injuries constitute a significant proportion of the reasons why employees are absent from work, it can be concluded that those who do not take part in the training program generally sustain more injuries than those who do. This is further depicted by the histograms for the two sets of employees.
