Mean = [number of observations]/[total number of observations]

For grouped data, mean is:

Mode: The mode is the number that appears most frequently in a set of data. We can find the mode by counting the number of times each value occurs in a data set.

Median for ungrouped data:

Median = [(n+1)/2]th observation, if n is odd.

Median = mean of (n/2)th observation and [(n/2)+1]th observation, if n is even.

Median: Median is the most middle value in a set of data. Let n denotes the number of observations in a data set. If n is odd, the median equals the [(n+1)/2]th observation.

Mode: To find the mode, arrange the given data in the ascending order. Then count how many times each number is occurring. The number that occurs most, is the mode

Mean deviation: It is the mean of the absolute values of the numerical differences between the numbers of a set and their mean or median.
