- 5class widthlargest value - smallest value
--------------------
desired no. of values that fall within a class - 6Class boundariesadd 0.5 to the upper class limit and subtract 0.5 from the lower class limit
- 7Class midpointlower class limit + upper class limit /2
- 8Relative class frequencyClass freq. (F)

- 11What is the class width?47- 1/6 = 7.6 -> 8
- 12What is the first class limit? Others too.1-8
- 13What are the class boundaries? (For first row).0.5-8.5
- 14What is the tally?14
- 15What is the frequency?14
- 16What is the class midpoint?1+8/2 = 4.5
