The measures of spread include the range, quartiles and the interquartile range, variance and standard deviation. Let's consider each one by one.
<u>Interquartile Range: </u>
Given the Data -> First Quartile = 2, Third Quartile = 5
Interquartile Range = 5 - 2 = 3
<u>Range:</u> 8 - 1 = 7
<u>Variance: </u>
We start by determining the mean, 

n = number of numbers in the set
Solving for the sum of squares is a long process, so I will skip over that portion and go right into solving for the variance.

5.3 
<u>Standard Deviation</u>
We take the square root of the variance,

2.3 
If you are not familiar with variance and standard deviation, just leave it.

Answer:
200 students are boys and rest of 400 are girls
Step-by-step explanation:
Given that:
Total students = 300
1/3 students of total are boys
so.
Boys = 1/3(600)
Boys = 200
For finding number of girls:
Girls = total - boys
Girls = 600 - 200
Girls = 400
