Two-Way Tables





 

Videos and lessons to help Grade 8 students understand that patterns of association can also be seen in bivariate categorical data by displaying frequencies and relative frequencies in a two-way table. Construct and interpret a two-way table summarizing data on two categorical variables collected from the same subjects. Use relative frequencies calculated for rows or columns to describe possible association between the two variables. 

For example, collect data from students in your class on whether or not they have a curfew on school nights and whether or not they have assigned chores at home. Is there evidence that those who have a curfew also tend to have chores?


Common Core: 8.SP.4

Suggested Learning Targets


  • I can recognize patterns shown in comparison of two sets of data.
  • I can show how to construct a two-way table.
  • I can interpret the data in the two-way table to recognize patterns. (For examples,
    collect data from students in your class on whether or not they have a curfew on
    school nights and whether or not they have assigned chores at home. Is there
    evidence that those who have a curfew also tend to have chores?).
  • I can use relative frequencies of the data to describe relationships (positive,
    negative, or no correlation).
