I wrote down some important stats concepts for you:

Basic numbers: Find out about basic number concepts. What is range?. What is frequency or count?

Central tendency: There can be various ways of expressing central tendency .... so check out median, mean, mode and their comparison.

Graphs: Do you know how to display data in graphs (and not just numbers)? Tables are just one way to view data .... check out line graphs, bar charts, and pie charts.

Are you ready to take a quiz about statistic concepts?
