This is an example of a cumulative frequency table.

Marks: 30, 31, 32, 33

Frequency: 5, 7, 10, 6

Solution:

Marks: 30. 31, 32, 33

Frequency: 5, 7, 10, 6

Marks less than: 30, 31, 32, 33

Cumulative Frequency: 5, 5+7=12, 12+10=22, 22+6=28

Question: What percentile would mark 32 be at, and what would the percentile mean. Please can you show the calculations so that I can understand better? Thank you.
