Check which data points (18,19,24,35,27,33,35,35,28,23) fall in 18 - 22. The values are 18, 19. So frequency is 2.

Step2: Analyze 23 to 27

Check data points in 23 - 27. Values: 23,24,27. So frequency is 3.

Step3: Analyze 28 to 32

Check data points in 28 - 32. Value: 28. So frequency is 1.

Step4: Analyze 33 to 37

Check data points in 33 - 37. Values: 33,35,35,35. So frequency is 4.
