The item which is repeated the maximum number of times in the data is called the mode or the modal value
Merits of Mode
1.) The logic behind its computation is easily understood.
2.) Even when some of the extreme values are missing, it can be easily computed.
3.) It can be calculated graphically.
Demerits of mode
1.) It is not directly based on all the values.
2.) It is not as stable as the arithmetic mean.
Note. Relation between Mean, Mode and Median
Mode = 3 Median - 2 Mean
Find the mode of the following data
14, 25, 14, 28, 18, 17, 18, 14, 23, 22, 14, 18
We make a frequency table for the data.
Mode = 14
