Common Core Standards*
S-IC-3: Recognize the purposes of and
differences among surveys, experiments and
observational studies; explain how
randomization applies to each.
S-ID-1: Represent data with plots (dot plots,
histograms, box plots)
S-ID-3: Interpret differences in shape, center
and spread in the context of the data,
accounting for possible effects of outliers
S-ID-3: Interpret differences in shape, center
and spread in the context of the data,
accounting for possible effects of outliers
S-ID-2: Use statistics appropriate to the shape
of the distribution to compare center (median,
mean) and spread (IQR, std. dev) of two or
more data sets
S-ID-4: Use the mean and standard deviation
of a data set to fit it to a normal distribution
and to estimate population percentages.
Recognize that there are data sets for which
such a procedure is not appropriate.
S-ID-4: Use calculators, spreadsheets, and
tables to estimate areas under the normal
curve.
S-IC-1: Understand statistics as a process for
making inferences about a population
parameter
S-IC-2: Decide if a specified model is
consistent with results from a given datagenerating process, e.g. simulation
Statistical Inference/Review
 In class – comparing ages of
actors/actresses
 Select project topics

Test
*Not covered: S-IC-4: Use data from a population survey to estimate a population mean or proportion; develop a
margin of error through the use of simulation models for random sampling.
S-IC-5: Use data from a randomized experiment to compare two treatments; use simulation to decide if differences are
significant
