In class students were introduced to contingency tables that showed the interaction between 2 variables. We can use a side-by-side bar chart, segmented bar graph or comparative pie charts to display the data.
Students were also introduced to marginal and conditional distributions. Marginal distribution is the distribution along one variable. Conditional distribution is the distribution of one variable along another.
If the conditional distribution = marginal distribution; we say the variables are independent. If conditional distribution ≠ marginal distribution we say there is an association between the two variables.
The notes are attached and the homework is listed below.
