Proportions are not Averages


Proportions are percentages but written as a decimal such as 0,5 for 50%. People often think of these as averages but they’re actually a little bit different.

Example of two bar graphs showing different proportions of males vs. females

In the above example, we have two data sets. In the first one, there is a score of 80% male and 20% female. In the second one, there is a score of 52% male and 48% female. Both of these data sets have the mode of male.

Even though both data sets have the same mode, it is clear to see that the proportions are vastly different.
