Concept One: Samples & Inferences
Standard(s) &
Essential Questions
MGSE7.SP.1 Understand that
statistics can be used to gain
information about a population
by examining a sample of the
population; generalizations
about a population from a
sample are valid only if the
sample is representative of that
population. Understand that
random sampling tends to
produce representative
samples and support valid
inferences.
E.Q How do you select a valid
sample to survey or study?
MGSE7.SP.2 Use data from a
random sample to draw
inferences about a population
with an unknown characteristic
of interest. Generate multiple
samples (or simulated samples)
of the same size to gauge the
variation in estimates or
predictions. For example,
estimate the mean word length
in a book by randomly sampling
words from the book; predict
the winner of a school election
based on randomly sampled
survey data. Gauge how far off
the estimate or prediction might
be.

Essential Questions
MGSE7.SP.2 Use data from a
random sample to draw
inferences about a population
with an unknown
characteristic of interest.
Generate multiple samples (or
simulated samples) of the
same size to gauge the
variation in estimates or
predictions.
E.Q. How can variation be
described within a data set?
MGSE7.SP.3 Informally
assess the degree of visual
overlap of two numerical data
distributions with similar
variabilities, measuring the
difference between the
medians by expressing it as a
multiple of the interquartile
range.
E.Q. How are proportions
used to estimate information
about populations?
MGSE7.SP.4 Use measures
of center and measures of
variability for numerical data
from random samples to draw
informal comparative
inferences about two
populations.
