Included Skills:

Demonstrate an understanding of the measures of central tendency and range for sets of data.
• Concretely represent mean, median, and mode and explain the similarities and differences among them.
• Determine mean, median, and mode for a set of data, and explain why these values may be the same or different.
• Determine the range of a set of data.

• Solve a problem involving the measures of central tendency.
• Analyze a set of data to identify any outliers.
• Explain the effect of outliers on the measures of central tendency for a data set.
• Identify outliers in a set of data and justify whether or not they should be included in the reporting of the measures of central tendency.
• Provide examples of situations in which outliers would and would not be used in reporting the measures of central tendency.
• Explain why qualitative data, such as colour or favourite activity, cannot be analyzed for all three measures of central tendency.
