• 1.C Sets and Venn Diagrams

• Use two-way tables.

• 5.C Statistical Tables and Graphs

• Decide if a statement involving statistical tables and graphs makes sense.

• Construct and interpret frequency tables.

• Determine whether a variable is qualitative or quantitative.

• Construct and interpret line graphs, bar graphs, pie charts, and histograms.

• Solve applications involving frequency tables and graphs.

• 5.E Correlation and Causality

• Decide if a statement involving correlation and causality makes sense.

• Interpret scatterplots.

• Determine whether variables are correlated.

• Create scatterplots.

• If X is correlated with? Y, what must be true about X and? Y? Explain your reasoning.

X causes Y. If Y increases as X? increases, then X must cause Y to change.

Increasing values of X go with either increasing or decreasing values of Y. A correlation exists between two variables when both variables increase or decrease together.

X causes Y. If Y decreases as X? increases, then X must cause Y to change.

Increasing values of X go with either increasing or decreasing values of Y. A correlation exists between X and Y when higher values of X consistently go with higher values of Y or when higher values of X consistently go with lower values of Y.

Increasing values of X go with increasing values of Y. A correlation exists between two variables when both variables increase together.

Increasing values of X go with increasing values of Y. A correlation exists between two variables when both variables decrease together.

Determine whether the following variable is qualitative or quantitative.

The? yes/no responses on a ballot initiative to the question "Should smoking in restaurants be"Should smoking in restaurants be prohibited question mark "prohibited?" nothing

The variable is quantitative because it is possible to count the number of responses and check that each voter gave only one.

The variable is qualitative because? yes/no responses on a ballot initiative are nonnumerical categories.

The variable is qualitative because a? voter's response on a ballot initiative depends on his or her opinions.

The variable is quantitative because the yes and no responses can be counted to determine the outcome of the initiative.

Which of the following best describes the correlation between accidents and texting while? driving? Explain your reasoning.
