Question

what is a mean, mode,median​

Answer 1

Mean, median, and mode are three kinds of "averages". There are many "averages" in statistics, but these are, I think, the three most common, and are certainly the three you are most likely to encounter in your pre-statistics courses, if the topic comes up at all.

The "mean" is the "average" you're used to, where you add up all the numbers and then divide by the number of numbers. The "median" is the "middle" value in the list of numbers. To find the median, your numbers have to be listed in numerical order from smallest to largest, so you may have to rewrite your list before you can find the median. The "mode" is the value that occurs most often. If no number in the list is repeated, then there is no mode for the list.

Answer 2

Heÿ!!

Mean => Mean of a number of observation is the sum of the values of all the observations divided by the total no. of observations

$mean \: \frac{x1 + x2.......xn}{n}$

Median => The central value of a statistical data if it is arranged in ascending or descending order.




Mode => It is the value x at which its probability mass function takes its maximum value.
