Question

mean median and mode its 5 o 6 example ..anyone

Answer 1

Hi friend!

Mean: Also known as Arithmetic Mean, it is used to calculate the average of a group of numerical values.
Now, if you wanna calculate your average percentage and all you have is your percentages in different subjects, you will use this A. M. (Arithmetic Mean)

E. g.: 75%, 86%, 90%, 79% & 80%
A. M. = $\frac{Total \: Value}{No. \: of \: observations}$
75 + 86 + 90 + 79 + 80 = 405
405/5 = 81%
A. M. = 81%

Mode: The observation which occurs the most number of times in a group of numerical values becomes the mode of that group.
Now, if you wanna calculate the number of, say, chapattis for a party, you will see how many chapattis do the majority of the people eat.

E. g.: 2, 3, 1, 4, 2, 2, 3, 1, 3, 2, 2, 5, 3, 4 & 1
You will make a frequency table for this (you know what's a frequency table right?) Then you will add the tally marks, which observation gets the highest number of tally marks is the mode of this group.

Here the observations are 1, 2, 3, 4 & 5

1 gets 3 points.
2 gets 5 points.
3 gets 4 points.
4 gets 2 points.
5 gets 1 point.

2 is the winner! So 2 is the mode here.

Now for the median,
What's a median?
The observation which occurs exactly at the center of a list of observations, when in the ascending or descending order, becomes the median. So, this depends on whether there are odd no. of observations or even.

E. g.: 4, 2, 4, 6, 8, 7, 6, 8, 4, 5, 10, 2, 15, 13 & 7
A. O. = 2, 2, 4, 4, 4, 5, 6, 6, 7, 7, 8, 8, 10, 13, 15

Here, the second 6 stands in the middle of the long 15 person queue.
So, 6 becomes the median.

Hope you understood the concept well, and found my answer useful. Keep Smiling!
