| Instructional
programs from prekindergarten through grade 12 should enable
all students to— |
In grades 6–8 all students should— |
| Formulate
questions that can be addressed with data and collect, organize,
and display relevant data to answer them |
| • |
formulate questions, design studies, and collect data
about a characteristic shared by two populations or different
characteristics within one population; |
| • |
select, create, and use appropriate graphical representations
of data, including histograms, box plots, and scatterplots.
|
|
| Select
and use appropriate statistical methods to analyze data |
| • |
find, use, and interpret measures of center and spread,
including mean and interquartile range; |
| • |
discuss
and understand the correspondence between data sets and
their graphical representations, especially histograms,
stem-and-leaf plots, box plots, and scatterplots. |
|
| Develop
and evaluate inferences and predictions that are based on
data |
| • |
use observations about differences between two or more
samples to make conjectures about the populations from
which the samples were taken; |
| • |
make conjectures about possible relationships between
two characteristics of a sample on the basis of scatterplots
of the data and approximate lines of fit; |
| • |
use conjectures to formulate new questions and plan new
studies to answer them. |
|
| Understand
and apply basic concepts of probability |
| • |
understand
and use appropriate terminology to describe complementary
and mutually exclusive events; |
| • |
use proportionality and a basic understanding of probability
to make and test conjectures about the results of experiments
and simulations; |
| • |
compute probabilities for simple compound events, using
such methods as organized lists, tree diagrams, and area
models. |
