MEAN
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
mean = 19.833... median = 19.5 mode = 19
mean is the average of numbers in the data set mode is the most frequently occurring value in a data set and median is the middle number of the data set so you would use mean
The mean is better than the median when there are outliers.
The median would not change, but the mean would increase.
That would provide some evidence that the distribution is symmetric about the mean (or median).

MEAN
The mean deviation from the median is equal to the mean minus the median.
An outlier will pull the mean and median towards itself. The extent to which the mean is affected will depend on the number of observations as well as the magnitude of the outlier. The median will change by a half-step.
I use it in class when looking at my student's scores... Often I look at mean, median, and mode to decide to reteach a concept or not.

who discovered mean median and mode
Mean, Median and Mode. They are three kinds of averages.
mean is the average of numbers in the data set mode is the most frequently occurring value in a data set and median is the middle number of the data set so you would use mean
