Analyze displays of bivariate data to develop or select appropriate claims about those data.

Clarifications:

Essential Understandings

Concrete:

  • Identify a similar distribution when given a choice of three (e.g., when shown a normal distribution, can select a second example of a normal distribution from three choices).
  • Identify the appropriate statement when given a relationship between two variables (may use graphic supports such as highlighted transparency of an association).
Representation:
  • Understand the following concepts and vocabulary: variable, claim, association, relative frequency, frequency, two-way table, categorical variable, bivariate
  • Explain the associations between the variables using supports (e.g., the selection of the highlighted transparency and make a statement).

Number: MAFS.8.SP.1.AP.4a Category: Access Points
Date Adopted or Revised: 06/14 Cluster: Investigate patterns of association in bivariate data. (Supporting Cluster)

Clusters should not be sorted from Major to Supporting and then taught in that order. To do so would strip the coherence of the mathematical ideas and miss the opportunity to enhance the major work of the grade with the supporting clusters.

Name Description
MAFS.8.SP.1.4: 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?
