Detailed explanation-3: -For a small data set, you first count the number of data points (n) and arrange the data points in increasing order. If the number of data points is uneven, you add 1 to the number of points and divide the results by 2 to get the rank of the data point whose value is the median.

The median is the middle value when a data set is ordered from least to greatest. The mode is the number that occurs most often in a data set.
