Included Skills: Stats
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. • Provide a context in which the mean, median, or mode is the most appropriate measure of central tendency to use when reporting findings and explain the choice. • 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.
