Day 127: Box-and-Whisker Plots

Math 6 and Math 6+ students worked with different data sets to create box-and-whisker plots. New vocabulary for today was: lower extreme, upper extreme, quartile one (median of lower half of data set), quartile two (median of the entire data set), quartile three (median of upper half of data set), upper extreme and interquartile range.

 

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

Math 6 and Math 6+:

• Display numerical data in plots on a number line, including dot plots (line plots), histograms, and box plots.
• 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.
