Introduction To Statistics

Class decoration program was to be organized in the school. The students of class 6th were not able to decide with what color to paint the walls inside the classroom. Light yellow, pink, light green and sky only four colors were available in his school.

On being called the class leader, all the students wrote their name and favorite color on a page. Which are shown in the following table -

Table - 01

No.	Students Name	Colors
01.	Mohan	Light Yellow
02.	Mohit	Pink
03.	Rina	Light Yellow
04.	Mina	Sky
05.	Rahim	Light Yellow
06.	Hemant	Light Green
07.	Raju	Light Green
08.	Rasmika	Sky
09.	Roshni	Light Yellow
10.	Basant	Sky
11.	Anamika	Light Green
12.	Sunil	Pink
13.	Ronnie	Light Yellow
14.	Shraddha	Light Yellow
15.	Sketch	Pink

On the basis of this information can you decide which color to paint the wall? Then suggest a way to Sunil. He wrote the names of the colors on the board and asked the student who liked each color to write his name against the color of his choice.

Now this list will become as follows:-

Table - 02

Colors	Students Name
Pink	Mohit, Sunik, Sketch
Light Yellow	Mohan, Rina, Rahim, Roshni, Ronnie, Shraddha
Light Green	Hemant, Raju, Anamika
Sky	Mina, Rashmika, Basant

Since the number of students who liked light yellow was the largest, therefore, it was decided by all the students to paint with this color.

Have you ever adopted this approach to decision making in daily life? Make a list of those who have scored more than 35% and less than 35% in each of the subjects in the quarterly examination of your class. Can you tell on this which subject has the best results and which subject has the worst?
