  • Stem-and-Leaf Plots
  • Dot Plots
  • Scatter Plots
  • Pie Charts
  • Pareto Charts
  • Mean, Median, Mode and Range of Quantitative Data
  • Weighted Mean of a Data Set and Mean of a Frequency Distribution
  • Variance and Standard Deviation (population or sample)
  • Empirical Rule
  • Quartiles and Interquartile Range (5-number summary)  with a Box-and-Whisker Plot
  • Fractiles (eg: percentiles, deciles)
  • Z-Scores
  • Probability Distribution
  • Discrete Probability Distribution
  • Expected Value of a Discrete Probability Distribution
  • Binomial Experiment
