Case 2: Formula

${P = \frac{DBM}{OVS} \times 100 }$

Where −

For a sample size of 30 if this percentage is greater than 33% there tends to be a difference between two groups.
For a sample size of 100 if this percentage is greater than 20% there tends to be a difference between two groups.
For a sample size of 1000 if this percentage is greater than 10% there tends to be a difference between two groups.

Describe the difference between following sets of data.

Sr. No.	Name	Set A	Set B
1	Max	12	15
2	UQ	10	13
3	Median	7	10
4	LQ	6	9
5	Min	5	6

Consider the following diagram:

${OVS = 13 - 6 \\[7pt] \ = 7 \\[7pt] \ DBM = 10 -3 \\[7pt] \ = 4 }$

Apply the formula

${P = \frac{DBM}{OVS} \times 100 \\[7pt] \ = \frac{4}{7} \times 100 \\[7pt] \ = 57.14 }$

As percentage is over 33% thus there is difference between Set A and Set B. It is likely that Set B is greater than Set A.
