What's the difference between mean and median?
Median is more reliable because it's less susceptible to the effects of outliers. For example, if you have a dataset with a few extremely high values, the mean would be skewed towards those values, making it less representative of the data. Median, however, would remain unaffected and provide a more accurate representation of the data.

However, there are also some potential risks to consider, such as:
The choice between mean and median depends on the nature of your data. If your data is normally distributed and doesn't contain outliers, mean might be the better choice. However, if your data is skewed or contains outliers, median would be a more suitable option.
In simple terms, mean refers to the average value of a set of numbers. To calculate the mean, you add up all the numbers and divide by the total count. For example, if you have the numbers 2, 4, 6, and 8, the mean would be (2 + 4 + 6 + 8) / 4 = 5. On the other hand, median is the middle value of a set of numbers when they're arranged in order. If you have the same numbers, the median would be 5, as it's the middle value.
Common Questions
The main difference between mean and median is how they're calculated and what they represent. Mean is sensitive to outliers, meaning that a single extreme value can significantly affect the result. Median, on the other hand, is more robust and less affected by outliers.
