|1. Use ratios, rates, proportional relationships, and scale
drawings to solve single- and multi-step problems.
student will use a proportional relationship between two variables to solve a
multi-step problem to determine a ratio or rate; calculate a ratio or rate and
then solve a multi-step problem; take a given ratio or rate and solve a
|2. Solve single- and multi-step problems involving percentages.
student will solve a multi-step problem to determine a percentage; calculate a
percentage and then solve a multi-step problem; take a given percentage and
solve a multistep problem.
|3. Solve single- and multi-step problems involving measurement
quantities, units, and unit conversion.
student will solve a multi-step problem to determine a unit rate; calculate a
unit rate and then solve a multi-step problem; solve a multi-step problem to
complete a unit conversion; solve a multistep problem to calculate density;
use the concept of density to solve a multi-step problem.
|4. Given a scatterplot, use linear, quadratic, or exponential
models to describe how the variables are related.
student will, given a scatterplot, select the equation of a line or curve of
best fit; interpret the line in the context of the situation; use the line or
curve of best fit to make a prediction.
|5. Use the relationship between two variables to investigate key
features of the graph.
student will make connections between the graphical representation of a
relationship and properties of the graph by selecting the graph that
represents the properties described; using the graph to identify a value or
set of values.
|6. Compare linear growth with exponential growth.
student will infer the connection between two variables given a context in
order to determine what type of model fits best.
|7. Use two-way tables to summarize categorical data and relative
frequencies, and calculate conditional probability.
student will summarize categorical data or use categorical data to calculate
conditional frequencies; conditional probabilities; association of variables;
independence of events.
|8. Make inferences about population parameters based on a sample
student will estimate a population parameter given the results from a random
sample of the population. The sample statistics may mention confidence
intervals and measurement error that the student should understand and make
use of, but need not calculate.
|9. Use statistics to investigate measures of center of data and
analyze shape, center, and spread.
student will calculate measures of center and/or spread for a given set of
data or use given statistics to compare two separate sets of data. The
measures of center that may be calculated include mean, median, and mode, and
the measures of spread that may be calculated include range. When comparing
two data sets, the student may investigate mean, median, mode, range, and/or standard deviation.
|10. Evaluate reports to make inferences, justify conclusions,
and determine appropriateness of data collection methods.
student will evaluate reports to make inferences, justify conclusions, and
determine appropriateness of data collection methods. The reports may consist
of tables, graphs, and text summaries.
