frequency density and cumulative frequency

Showing 1 to 4 of 4

does anybody happen to have any notes on these? including histograms, mean = fx/x etc? thank you :)

well cumulative frequency is the frequency added up class by class and frequency density is frequency divided by class width

try this

on graphs, cumulative frequency: plot at TOP of range!
frequency: plot at MIDDLE of range!
on histograms: it's the area that determines the frequency :)
