Is mean ever better than median?

The answer is simple. If your data contains outliers such as the 1000 in our example, then you would typically rather use the median because otherwise the value of the mean would be dominated by the outliers rather than the typical values. In conclusion, if you are considering the mean, check your data for outliers.

Why would the mean be larger than the median?

But if a distribution is skewed, then the mean is usually not in the middle. Notice that in this example, the mean is greater than the median. This is common for a distribution that is skewed to the right (that is, bunched up toward the left and with a “tail” stretching toward the right).

Can the median be lower than the mean?

The median of a set of numbers is the value that is in the middle (In a set with an odd number of values, it’s the middle value. In fact, the mean will be lower than the median in any distribution where the values “fall off”, or decrease from the middle value faster than they increase from the middle value.

What does the difference between mean and median indicate?

The Difference Between Mean and Median The mean is the average you already know: just add up all the numbers, then divide by the number of numbers. The median is the middle value in a list of numbers.

Where mean and median both terms should be used?

When you have a symmetrical distribution for continuous data, the mean, median, and mode are equal. In this case, analysts tend to use the mean because it includes all of the data in the calculations. However, if you have a skewed distribution, the median is often the best measure of central tendency.

Why is it called mean instead of average?

A statistician or mathematician would use the terms mean and average to refer to the sum of all values divided by the total number of values, what you have called the average. This especially true if you have a list of numbers. There are times however that this is called the mean.

Is median the average?

What is the median? The median is another form of an average. It usually represents the middle number in a given sequence of numbers when it’s ordered by rank.
