Day 126: Summarizing Data Sets with Mean, Median, Mode, and Range

Math 6 and Math 6+ students today worked with measures of center and measures of variability. Students learned how to calculate the mean, arrange data to determine the median, and use subtraction to calculate the range.

Skills that were introduced, modeled, practiced, and informally/formally assessed today in class include:

Math 6 and Math 6+:

• Recognize and formulate a statistical question as one that anticipates variability and can be answered with quantitative data.
• Find the quantitative measures of center (median and/or mean) for a numerical data set and recognize that this value summarizes the data set with a single number. 
• Interpret mean as an equal or fair share. 
• Find measures of variability (range and interquartile range) as well as informally describe the shape and the presence of clusters, gaps, peaks, and outliers in a distribution.
