Mode in Grade VIII

Previously we have discussed about calculus problem solver and In today's session we are going to discuss about Mode which comes under gujarat board textbooks online, Its mathematical term that comes in statistics. It can be defined as particular value that occurs most number of the times in a list. In simple words mode is a most frequent value in a data set or most common value in a group. Mode or statistical mode is same thing. Let us understand mode with an easy example:-

We have a list of numbers :- 3, 5, 7, 2, 8, 9, 2, 4, 2

The first step to find mode is to arrange the list in ascending order than we will get.

2, 2, 2, 3, 4, 5, 7, 8, 9

The next step to find out particular number that has occurred most number of times.

Here the particular number is 2.

So the mode will be 2.

Mode is used to collect information about non-deterministic numbers, also called random numbers in a single quantity.

Now let us discuss how calculate mode when list is fractional with an example:-

Now we are talking a example of fraction list :- 3.2, 3.7, 4.1, 3.2, 5.6, 2.4, 3.2, 2.4

First of all arrange the list in an ascending order:- 2.4, 2.4, 3.2, 3.2, 3.2, 3.7, 4.1, 5.6

3.2 is a number that has occurred most number of times in the above list.

So the mode is 3.2

Advantage of mode

-provide support to mean,median to solve statistical problems.

-to identify wether an event has occurred more than one time or not.

-used for counting the number of times

Note:- A mode will not exist if there is no repetition of any number in a list. A list contain may be more than one mode if two numbers sharing same occurrence of time

The above described mode information will be truly helpful for grade VIII students.
