  • Students will represent real-world data using a histogram and box and whisker diagram.
  • Students will calculate measures of central tendency and spread.
  • Students will compare distributions from two data sets and draw conclusions.
  • Students will identify and analyze outliers in a data set.


  • Histogram
  • Outlier
  • Box and Whisker Diagram
  • Skew
  • Median
  • Interquartile Range
