Suitable for Grades: 8th Grade
CCSS: 8.SP.A.4
CCSS Description: 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?
Following on from the worksheet called Reading from Two Way Tables, this worksheet gives learners practice in producing or completing two way tables. Section A provided an array of triangles and quadrilaterals which need to be categorized in a two way table based on the number of sides and whether they have a right angle. Section B provides information about the eye color of grade 3 and grade 4 children where clues to each box of the table must be used in its completion. Section C contains a mixture of written information and some values in a table which needs to be completed.
