The mean, median, and mode are important ways to understand numbers in statistics. Each one helps us see the data in a different way.

1. Mean: This is what most people think of as the average. To find the mean, you add up all the numbers and then divide by how many numbers there are. For example, if you have the numbers $2, 3, 5$, you would add them: $(2 + 3 + 5) = 10$. Then, you divide by $3$ (because there are three numbers). So, the mean is $10 / 3 = 3.33$.

2. Median: The median is the middle number when you put all your numbers in order. For the set $2, 3, 5$, the middle number is $3$. If you have an even set, like $2, 3, 5, 7$, you find the median by taking the two middle numbers ($3$ and $5$) and finding their average. So, the median is $(3 + 5) / 2 = 4$.

3. Mode: The mode is the number that shows up the most often. In the set $2, 3, 3, 5$, the mode is $3$ because it appears twice. If every number is different, then there is no mode.

In short, the mean gives you the overall average, the median shows you the middle point, and the mode tells you which number is the most common.
