fill in the blanks:
4. in any __________ the value that appears the most is called as the mode.
5. Mode is that point in the distribution where there is highest ___________ .
6. in our daily life we often hear that the average height of an indian is ___________ .
Characteristics of Mode
there are following characteristics of mode based on the above description-
1. Mode is based on all the elements of the series therefore, there is no effect of very small as
well as very big value element on it.
2. Mode depends on frequency. therefore, instead of value of elements, it is based on the value
of frequency of that element that has the highest frequency. therefore, it is the smallest way
to find out the mode,
3. Mode is not the highest value element but it can be the value of the element.
4. There is difficulty in finding out the mode in condition where there are two or more than two
elements with the same highest frequency, in such a situation we have to describe more than
two modes. for example- 1, 3, 4, 4, 6, 7, 6, 10, 7, 4, 7 we have 4 and 7 as the mode.
Computation of Mode
Normally it is said that computation of mode is very easy because it is value of the element that has
the highest frequency. Therefore, by arranging any series in a systematic order we can find out which
element has the highest frequency. With the help of given examples we will focus on the methods of
calculating mode.
Mode of Simple Series
Calculation of mode in a simple series is very easy because in this the elements are arranged in the
definite order according to their values and the element that has the highest frequency is the mode.
this can be made clear with the help of the following example-
Example 12 find the mode of given series
33,20, 35, 50, 37, 33, 35, 25, 35, 34 and 35
solution: By arranging the elements according to their values, the situation will be like this-
20, 25, 33, 33, 34, 35, 35, 35, 35, 37, 50.
from the above order it is clear that 35 appears the most therefore it has the highest frequency.
therefore, the mode of given series is 35.
Mo = 35
Notes the symbol for mode is sometimes used as Z instead of Mo.
