Contributed by StemPy LabTry it on paper first. A hint, the key idea and the worked solution are here when you need them.
Which average, the mean, the median or the mode, would you use for each?
- A bakery decides which cake to bake the most of.
- The typical time to finish a marathon, when a few people walk very slowly at the end.
- Sharing a prize of 5,000 rupees equally among 4 winners.
- The most common way that students come to school.
Need a reminder? The key ideaShow
The mean is the fair share, the median is the middle and the mode is the most common. An outlier drags the mean but hardly moves the median.
The worked solution
Have you tried it?
Work it out on paper first. It is fine to get stuck or make a mistake: that is how we learn. When you are ready, go through the solution one step at a time, and check each step against your own.
Step 1. (a) The most popular cake: the mode.
Step 2. (b) A few very slow times would drag the mean: the median.
Step 3. (c) A fair share: the mean, rupees each.
Step 4. (d) Ways of travelling are words: the mode.
