Measures of Central Tendency and Stem/Leaf Plots

Several students presented their extra credit projects this afternoon. Skits, songs, and videos were shared, and all were well done. Thanks to all who accepted the challenge.

As we begin a short unit on statistics, we reviewed the meaning of the words mean, median, mode and range. We next measured indivdual heights and arm spans, and recorded the data from the entire class in a stem and leaf plot. Students will use the data in their homework.

Tonight's Homework: Read Lessons 6.6 (about stem and leaf plots) and 6.7 (about box and whisker plots). Determine the mean, median, mode and range for the two sets of data collected in class today.
