Strand: STATISTICS - Interpreting Categorical and Quantitative Data (S.ID)

Summarize, represent, and interpret data on a single count or measurement variable. While students may have heard of the normal distribution, it is unlikely that they will have prior experience using it to make specific estimates. Build on students' understanding of data distributions to help them see how the normal distribution uses area to make estimates of frequencies (which can be expressed as probabilities). Emphasize that only some data are well described by a normal distribution (Standard S.ID.4).

Standard S.ID.4

Use the mean and standard deviation of a data set to fit it to a normal distribution and to estimate population percentages. Recognize that there are data sets for which such a procedure is not appropriate. Use calculators, spreadsheets, and tables to estimate areas under the normal curve.

  • Accuracy of Carbon 14 Dating I
    This task examines, from a mathematical and statistical point of view, how scientists measure the age of organic materials by measuring the ratio of Carbon 14 to Carbon 12. The focus here is on the statistical nature of such dating.
  • Do You Fit In This Car?
    This task requires students to use the normal distribution as a model for a data distribution. Students must use given means and standard deviations to approximate population percentages.
  • Introduction to the Materials (Math 3)
    Introduction to the Materials in the Mathematics Three of the The MVP classroom experience begins by confronting students with an engaging task and then invites them to grapple with solving it. As students ideas emerge, take form, and are shared, the teacher orchestrates the student discussions and explorations towards a focused mathematical goal. As conjectures are made and explored, they evolve into mathematical concepts that the community of learners begins to embrace as effective strategies for analyzing and solving problems.
  • Module 9: Statistics - Student Edition (Math 3)
    The Mathematics Vision Project, Secondary Math Three Module 9, Statistics, begins with a learning cycle where students construct the concept of normal distributions, understanding the effect of modifying either the mean or standard deviation.
  • Module 9: Statistics - Teacher Edition (Math 3)
    The Mathematics Vision Project, Secondary Math Three Module 9, Statistics, begins with a learning cycle where students construct the concept of normal distributions, understanding the effect of modifying either the mean or standard deviation.
  • Musical Preferences
    The basic idea is for students to demonstrate that they know what it means for two variables to be associated.
  • Representing Data 1: Using Frequency Graphs
    This lesson unit is intended to help educators assess how well students are able to use frequency graphs to identify a range of measures and make sense of this data in a real-world context.
  • Representing Data 2: Using Box Plots
    This lesson unit is intended to help educators assess how well students are able to interpret data using frequency graphs and box plots.
  • SAT Scores
    This task is designed to help students use the mean and standard deviation of a data set to fit it to a normal distribution and to estimate population percentages. They should also recognize that there are data sets for which such a procedure is not appropriate, and use calculators, spreadsheets, and tables to estimate areas under the normal curve.
  • Should We Send Out a Certificate?
    The purpose of this task is to have students complete normal distribution calculations and to use properties of normal distributions to draw conclusions. The task is designed to encourage students to communicate their findings in a narrative/report form in context not just simply as a computed number.
  • Statistical Analysis to Rank Baseball Players
    In this videotaped lesson students rank the greatest NY Yankee homerun hitters using statistical analysis. (6 minutes)
  • STATISTICS - Interpreting Categorical and Quantitative Data (S.ID) - Sec Math III Core Guide
    The Utah State Board of Education (USBE) and educators around the state of Utah developed these guides for the Secondary Mathematics III - Interpreting Categorical and Quantitative Data (S.ID).
