whenever I do practice papers for maths, I have noticed that i pretty much always get the questions about:
histograms, interquartile range, median, box plots, graphs etc wrong.

how should I revise these topics?
make a poster? do more questions? watch a video?

thankyou!

What are you getting wrong? Do you understand the idea of a histogram with frequency density?

I feel like there are so many things to remember. for example, when doing the median for frequency tables, it is completely different from doing the median for cumulative frequency and box plots. It's just remembering what to do and how to find specific things from a graph.
When I do AQA past papers, these questions seem to come up at least once within each paper and I do tend to get them wrong.

So I think you are getting confused between ffrequency tables where you have single values and grouped frequencies where there is a range of values.

Can you post an example and try to pinpoint the exact issue?
