Common Core Algebra I. Two Way Frequency Tables. Part of an Algebra 1 course but suited for this Geometry unit.
A Youtube video by eMathInstruction. In this lesson you learn about categorical data and how it can be organized in two way frequency tables. Relative frequency terminology, including join, marginal and conditional is taught in context. Associations between categories is explored.
In this Youtube video from MathBootcamps, we use mock survey data to show how you can find conditional probabilities. The wording on these can be important, so we look at questions that are worded in slightly different ways. Finally, we see how conditional probability can be used to determine if two events are independent or dependent.
