The document is a presentation about calculating measures of central tendency (mean, median, mode, and range) from a set of data. It instructs students to visit websites that define these terms and watch video clips explaining them. Students are then asked to complete a quick vocabulary check, an assessment quiz, and optional enrichment activities about measures of central tendency. The presentation provides support materials for teachers on math objectives covering finding and using measures of central tendency and spread to analyze statistical data.

1. 1. The Question As previously discussed, we have been working on calculating the mean, median, mode and range from a set a data. After completing this power point presentation you will be able to answer questions similar to the one below.
