   What is the median in math?

   • The median is the middle number in an ordered data set.
   • The mean is the sum of all values divided by the total number of values.

   Scores of group of students                        Frequency

                   1                                                           0

                   2                                                          2

                   3                                                          2

                   4                                                          4

                   5                                                          3

                   6                                                          1

                   7                                                          1

   First three set of scores from 1 to 3 comes under first quartile.

   Median is in the center.

   Last three set of scores comes under third quartile.

   Therefore, the first quartile would be drawn at 3.

   And the median would be drawn at 4.
