Many students find it tricky to understand the differences between mean, median, and mode in statistics. Let's clear up some common misunderstandings:
Mean means average: The mean is often called the average, but it can be affected by unusual numbers called outliers. For example, if we look at the numbers {1, 2, 2, 3, 100}, the mean is . But if we check the median, it is .
All three measures are the same: This is only true for perfectly even data. In real life, the mean, median, and mode can be different, especially when the data is uneven.
Mode is always one number: A set of data can have more than one mode or even none at all. For example, in the group of numbers {1, 2, 3, 3, 4, 4}, both and are modes.
Understanding these concepts can help you tackle statistics with confidence!
