In the appropriate context, they do.
Mean.
Average. this is because the typical is what the total divided by the number of items. this is also what the mean (or average) is.
For some kinds of distributions one, for others kinds, the other.
people or items chosen accurately reflect the group as a whole
The mean deviation from the median is equal to the mean minus the median.
NO mean: (average)add all the numbers, then divide by how many numbers you added!! Median: you have to put allthe numbers in order and then get the middle number and if there are two middle numbers add them and divide them by two!!
The three commonly used measures of central tendency are the mean, the median, and the mode. They are different ways of describing a "typical" member of the population.
In typical statistical distributions, these are measures that tend to lie close to the centre of the distribution.
The median of 65 and 90 is the same as their mean: 77.5The median of 65 and 90 is the same as their mean: 77.5The median of 65 and 90 is the same as their mean: 77.5The median of 65 and 90 is the same as their mean: 77.5
The median is 5, because two values (2 and 2) are less than 5, and an equal number of values (8 and 9) are greater than 5. Generally speaking, the median is more informative than the average (mean), although a proper calculation of a "typical value" of a list of values depends on what the typical value will be used for.
Mean, Median and Mode. They are three kinds of averages.
