Answer: The following are the three categories of average:
- The ratio of the sum of all values to the total number of values in a data set is known as the mean.
Formula:
- When the data are sorted in either ascending or descending order, the median is the midway value.
(i) The median of an arranged data set is the (n+1 / 2)th term when the number of terms in the data set is odd.
(ii) When a data collection has an even number of terms, the median is
where n is the total number of observations.
- The most prevalent number in the data collection is called the mode.
The connection between the three averages kinds is Mode =3( Median )-2( mode ).
