Standard(s) Taught 

MAFS.7.SP.2.3
Informally assess the degree of visual overlap of two numerical data distributions with similar variabilities, measuring the difference between the centers by expressing it as a multiple of a measure of variability.
MAFS.8.SP.1.4
Understand that patterns of association can also be seen in bivariate categorical data by displaying frequencies and relative frequencies in a twoway table. Construct and interpret a twoway table summarizing data on two categorical variables collected from the same subjects. Use relative frequencies calculated for rows or columns to describe possible association between the two variables.
MAFS.7.G.1.2
Draw (freehand, with ruler and protractor, and with technology) geometric shapes with given conditions. Focus on constructing triangles from three measures of angles or sides, noticing when the conditions determine a unique triangle, more than one triangle, or no triangle.
MAFS.7.G.2.5
Use facts about supplementary, complementary, vertical, and adjacent angles in a multistep problem to write and solve simple equations for an unknown angle in a figure.

Learning Targets and Learning Criteria 

Students are successful when they can…
 compare two data sets for variability by comparing graphs and explain the significance of any visual overlap.
 explain in writing why it makes sense that the greater the variability, the more visible the overlap on graphs presenting two numerical data sets.
 model and compare two realworld data sets by measuring the difference between centers and expressing it as a multiple of a measure of variability.
 understand the use of a twoway table to display bivariate categorical data.
 create a twoway table to record the frequencies of bivariate categorical values.
 determine the relative frequencies for rows and/or columns of a twoway table.
 use the relative frequencies and context of the problem to describe possible associations between the two sets of data.
 draw geometric shapes with given conditions.
 construct triangles from three measures of angles or sides.
 describe when angle measures determine a triangle (given angles equal 180)
 describe when side measures determine a unique triangle (a + b > c) or (a + b < c).
 determine whether three angle measures of three side lengths can form a triangle.
 discover the definitions of supplementary, complementary, vertical, and adjacent angles.
 solve multistep problems by applying what you know about the types of angles.
