What represents the average of a data set?

What is the best measure of average?
Mean is generally considered the best measure of central tendency and the most frequently used one. However, there are some situations where the other measures of central tendency are preferred.
Which is the best average to understand the data?
For normally distributed data, all three measures of central tendency will give you the same answer so they can all be used. In skewed distributions, the median is the best measure because it is unaffected by extreme outliers or non-symmetric distributions of scores. The mean and mode can vary in skewed distributions.
What represents the average?
The most widely used method of calculating an average is the ’mean’. When the term ’average’ is used in a mathematical sense, it usually refers to the mean, especially when no other information is given. Add the numbers together and divide by the number of numbers. (The sum of values divided by the number of values).
How do you find the average of a set of data?
The average of a set of numbers is simply the sum of the numbers divided by the total number of values in the set. For example, suppose we want the average of 24 , 55 , 17 , 87 and 100 . Simply find the sum of the numbers: 24 + 55 + 17 + 87 + 100 = 283 and divide by 5 to get 56.6 .

Which is a better measure median or average?
Conclusion. If the data you are comparing is mostly uniform then you can safely use the average (AVG) aggregator. However, if your number set has some outliers then you need to consider using median (MED) to filter out the values that are skewing the results.
Is mean the best average?
Therefore the mean is not the best ’average’ to use in this case. The median, on the other hand, really is the middle value. 50% of values are above it, and 50% below it. So when the data is not symmetrical, this is the form of ’average’ that gives a better idea of any general tendency in the data.
Which measure of average is best?
The mean is the most frequently used measure of central tendency because it uses all values in the data set to give you an average. For data from skewed distributions, the median is better than the mean because it isn’t influenced by extremely large values.
