When the values of all items of a series are arranged in increasing ascending or decreasing descending order it is usually called an array and the middle item of an array is called median.

The median divides the series into two groups; one group in which the values of items are less than the middle value and the other group in which the values of the items are greater than the middle item.

Median is denoted by Me or Mdn. The methods of calculating the median are comparatively simple. The value of median is not affected by change in extreme values.

If the number of data in a series is odd, the median is the middle value. But if the number of data in a series is even, the median is the average of the two middle values.

Methods of Determining Median: For unclassified and un-tabulated data: In order to calculate the median, the data are first arranged in increasing or decreasing order and then the following formula is used: The heights in cm for 9 plants are given below. Find out the Media Height — 67, 65, 70, 68, 62, 63, 64, 63, The height measurements can be arranged in ascending order as follows: The median is calculated as follows: The number of flowers recorded on 10 plants are: Find out the median value of flowers per plant.

The given numbers of flowers on 10 plants can be arranged in ascending order as under: Calculate the median of the following series of data obtained by measuring the heights of 16 plants: The given data of plant heights are arranged in ascending order as follows: To calculate the median for discrete grouped data, first of all the cumulative frequency of whole series is obtained.

Calculate the median of the following data obtained by counting the number of flowers on 19 plants. Calculate the median for the following data recorded for height in cm of 80 plants. The class values for cumulative frequencies 40 and 41 are included in the class value of cumulative frequency 45 which is The median is determined in the following way: The number of seeds produced by 55 plants of a plot are given in the following table.

Calculate the median seed number of a plant.MERITS AND DEMERITS OF MODERN EDUCATION. Let's try to describe in detail the primary education methods in this essay.
