3. Median

The median is that value that separates an ordered set of data

48. The median is

rd
Median is in 3 position in above set of data. Thus, the
median is 42.

4. Mode

The mode is the most frequently occurring value. The data
point(s) that occur(s) most frequently. There may be no mode
or more than one mode in the set of data.

For example in the data set 33, 38, 42, 45, 48, there is no mode.

Example:

Following are the test scores of 10 students.

18, 21, 22, 22, 22, 23, 23, 25, 26, 30. Calculate the mean, median
