Mathematics (2019) Grade(s): 09-12 - Geometry with Data Analysis

MA19.GDA.10
Use statistics appropriate to the shape of the data distribution to compare and contrast two or more data sets, utilizing the mean and median for center and the interquartile range and standard deviation for variability.

Unpacked Content

Knowledge

Students know:

Techniques to calculate the center and spread of data sets.
Techniques to calculate the mean absolute deviation and standard deviation.
Methods to compare data sets based on measures of center (median, mean) and spread (interquartile range and standard deviation) of the data sets.

Skills

Students are able to:

Accurately find the center (median and mean) and spread (interquartile range and standard deviation) of data sets.
-Present viable arguments and critique arguments of others from the comparison of the center and spread of multiple data sets.
Explain their reasoning on how standard deviation develops from the mean absolute deviation.

Understanding

Students understand that:

Multiple data sets can be compared by making observations about the center and spread of the data.
The center and spread of multiple data sets are used to justify comparisons of the data.
Both the mean and the median are used to calculate the mean absolute and standard deviations
