When should one of mean, mode, and median be used over the other
In: 15
If you have 5 dogs and one of them has 3 legs, the average (mean) number of legs is 19/5=3.8 legs.
But none of the dogs actually has 3.8 legs. Most people would say that an ordinary “average” normal dog has 4 legs. The mode and the median are both 4 legs. Median an mode are better at telling you how many legs an average dog has.
The mode is the number that comes up most, so that’s easy. The median is the middle number if you line the numbers all up. In this case: 3,4,4,4,4. It’s still 4.
