mode

What is Mode? Mode in statistics is used to define or find the value among the set of the data that is occurs most frequently. Mode is used to find the value for a distribution or a raw or unimplemented data set (play data analysis worksheets) that have the maximum frequency. For defining the mode of a give data set is explained in the term which has the maximum number of occurrences in the data set thus the mode of a given data set is the value around which the values of the variable are clustered densely.
For computing the mode of a series of individual operation, we first convert it into the discrete series frequency distribution by preparing the frequency table. From the frequency table we can identify the value having the maximum frequency. The value of the variable so obtained is the mode or the modal value.
We can take some example of understand the mode for following data find mode:
120 , 110 , 130 , 110 , 120 , 140 , 120 , 130 , 140, 120 .
The solution of these data is defined as:
Value (v): 110 120 130 140
Frequency (f) 2 4 2 2.
In this example we observe the value 120 has the maximum frequency then mode (get more details here) or modal value is 120.
There is one other example that defines it as a given set of numbers has mode 25 then the value find as follows:
15, 20, 25, 18, 14, 15, 25, 15, 18, 16, 20, 25, 20, x, 18:
Values (v): 14 15 16 18 20 25 x,
Frequency (f): 1 3 1 3 3 3 1
Then the mode for a given set of data is 25 so it have the maximum frequency this is possible when x = 25. So the value of x = 25.
