Introduce the new terms listed below:
• Interquartile Range (IQR)
• Standard Deviation
• Range Rule of Thumb
• Empirical Rule
• Chebyshev’s Theorem
• Coefficient of Variation
Give examples so that the learner can practice distinguishing between the new terms. At this point, the following topics are presumed to be prior knowledge. However, a link to an appropriate review packet may be useful in some cases.
• Frequency Distribution
Explains the different measures of variation with examples.
Explains how to find the measures of variation with the TI 83/84 Calculator.
Discusses the different Rules and Theorems for measures of variation. Includes coefficient of variation (CV).
