Day 143: Test Prep / Test

Students in Math 6 were given a collection of data and asked to construct multiple graphical representations using the same data.

A second, smaller data set was then given for students to calculate measures of center and variability.

Math 6+ students were administered the Topic Eight: Statistics posttest.

Today's learning objective(s):

• Recognize a statistical question as one that anticipates variability in the data related to the question and accounts for it in the answers. For example, "How old am I?" is not a statistical question, but "How old are the students in my school?" is a statistical question because one anticipates variability in students' ages.
• Understand that a set of data collected to answer a statistical question has a distribution which can be described by its center, spread, and overall shape.
• Recognize that a measure of center for a numerical data set summarizes all of its values with a single number, while a measure of variation describes how its values vary with a single number.

• Summarize and describe distributions.

• Display numerical data in plots on a number line, including dot plots, histograms, and box plots.
• Summarize numerical data sets.
• Give quartile measures of center and variability.
