State Curriculum Toolkit

Tools aligned to State Curriculum indicators and/or objectives.

  • Clarification of Indicator and/or Objective
    Explanation and/or examples of indicator and/or objective
  • Sample Assessments
    Items and annotated student responses as appropriate
  • Public Release Items
    Actual MSA items and annotated student responses as appropriate

Standard 4.0 Knowledge of Statistics

Students will collect, organize, display, analyze, or interpret data to make decisions or predictions.

Topic

A. Data Displays

Indicator

  • 1. Organize and display data
Objectives
  1. Organize and display data using back-to-back stem-and-leaf plots
    Assessment limit: Use no more than 20 data points using whole numbers (0–99)
  2. Organize and display data to make circle graphs

Topic

B. Data Analysis

Indicator

  • 1. Analyze data
Objectives
  1. Recognize and analyze faulty interpretation or representation of data
    Assessment limit: Use the choice of graphical display or the scale as leading to faulty interpretation or representation of data
  2. Determine the best choice of a data display
    Assessment limit: Use a given data set
  3. Analyze misleading data representation

Indicator

  • 2. Describe a set of data
Objective
  1. Analyze measures of central tendency to determine or apply mean, median, mode
    Assessment limit: Use no more than 15 pieces of data for the mean or median; or 15 to 30 pieces of data for the mode, using whole numbers or decimals with no more than 2 decimal places (0 – 100)

Note: Highlighted assessment limits will be tested in the no calculator section of MSA. In the assessment limit, (0-10) or (-10 to 10) means all numbers in the problem or the answer will fall within the range of 0 to 10 (including endpoints) or -10 to 10 (including endpoints), respectively. All content standards are tested in MSA but not all objectives. Objectives that have an assessment limit are tested on MSA. Objectives without an assessment limit are not tested on MSA.
