Unit Description
This unit engages the
students in the process of data investigation: posing questions, collecting
data, analyzing data, and making interpretations to answer questions. It focuses on ways of representing and
analyzing data and measures of center.

Enduring Understandings
· Understanding how to
read, write, organize, and compare numbers in various ways help me to make
sense of the world.
· Statistical analysis
and data display often reveal hidden patterns.
· Data analysis often
reveals patterns and enables predictions.
|
Essential Questions
·

Students will be able
to…
·
Develop an understanding of and strategies for collecting
and organizing categorical and numerical data
·
Develop an understanding of and strategies for displaying
data that are useful to show the overall distribution (or “shape”) of the
data as well as to see what kind of relationships may exist between data
about different characteristics (e.g., coordinate graph)
·
Calculate the range, mode, median, and mean of a set of
data
·
Make informed and reasoned conclusions about what is
typical in a data set based on its shape, range, measures of center, mode,
and mean
