Box and whiskers plots use five number summaries. The first number is:
1:Minimum
2.Quartile 1
3.Mean
4.Quartile 2
5.maximum
Quartile are simple to get.
If your set of numbers is:
2,3,3,6,8,8,11
Then find the mean
2 3 3 |6| 8 8 11
Find the mean of the left side of of mean.
2 |3| 3 3 =Quartile 1
Then the right side
8 |8| 11 8 =Quartile 2
-----------------------------------------------
Your 5 number summary is 2,3,6,8,11
Plot them on the number line, but put a line above where the dot would go. take the 3 middle lines and connect to make a box. The lines on the outside of the box are the whiskers, AKA distributed data.
Answer:

Answer:
<em>680</em>
Step-by-step explanation:
Given that:
All the pupils at a primary school come from one of three villages: Elmswell, Haughley or Woolpit.
of the pupils come from Elmswell
of the pupils come from Haughley
102 pupils come from Woolpit.
To find:
Total number of pupils in the school.
Solution:
Let total number of pupils = 
So, number of pupils that come from Elmswell = of 100x
OR
And, number of pupils that come from Haughley= of 100x
OR
Number of pupils that come from Woolpit = 
As per given statement:
Number of pupils from Elmswell = 25x = 25 
6.8 = 170
Number of pupils from Haughley = 60x = 60 6.8 = 408
Total number of pupils at the school =
