A2.D.2.1 Evaluate reports based on data published in the media by identifying the source of the data, the design of the study, and the way the data are analyzed and displayed. Given spreadsheets, tables, or graphs, recognize and analyze distortions in data displays. Show how graphs and data can be distorted to support different points of view. 


In a Nutshell

Students will analyze statistical data from different sources and investigate their origin to recognize any distortions of the data.

Student Actions

Teacher Actions

  • Students will develop mathematical reasoning to analyze statistical data and reports to identify any distortions due to data collection errors or data display manipulation.

  • Students will communicate mathematically about graphs from statistical data to recognize how they can be distorted to support contradicting views. 

 

  • Facilitate discourse among students by allowing students to explain and defend any data distortion finding they see within a study.

  • Pose purposeful questions as students represent statistical data with graphs that would promote different conclusions.

  • Implement tasks where students  research using the internet, magazines, newspapers, etc and locate graphs from statistical data that have been or could possibly have been distorted.

Key Understandings

Misconceptions

  • Identify the purpose of reports or published data in the media. 
  • Determine how the authors collected the data. 
  • Ascertain whether the collection methods in a given study are appropriate and unbiased. 
  • Understand when the data has been distorted to support different points of view.
  • Know that participants of a study as well as founders of the study can create bias.
  • Analyze different statistical data representations and realize that they can be manipulated to support different points of view.

  • Students fail to make a connection between the image of the graph and the data it represents. 
  • Students are unaware of how bias can lead to a faulty conclusion.
  • Students do not understand the different methods of data collection.
