This
two-part
activity
provides
an
introduction
to
the
basics
of
measurement
(linear,
mass,
volume,
density)
and
discusses
the
role
of
inferential
statistics
in
comparing
any
two
measurements.
The
concept
of
random
variations
in
measurements
is
introduced,
which
leads
to
a
discussion
of
binomial
distributions
and
probability
in
comparing
measurements
and
results.
Students
will
use

Statistics
play
a
vital
role
in
the
scientific
enterprise.
This
activity
provides
background
information
and
tutorials
on
basic
statistics
(mean,
median,
standard
deviation,
etc.)
used
in
science.
Topics
include
descriptive
statistics
(measures
of
central
tendency
and
dispersion)
and
presenting
data
(tables,
figures,
and
graphs).
Sample
datasets
from
actual
scientific
experiments
are
used
to
illustrate

This
lesson
reinforces
the
idea
that
Earth's
population,
including
the
population
of
the
United
States,
is
gowing
at
a
dramatic
rate.
It
discusses
some
of
the
basics
of
demography,
the
study
of
population
and
its
changes,
and
introduces
key
terms
used
to
describe
a
population.
The
lesson
inlcudes
an
activity
in
which
students
use
an
online
reference
to
look
up
some
population
statistics
and

One
of
the
primary
tools
that
demographers
use
to
understand
population
is
the
age
structure
diagram,
a
graphic
representation
that
shows
the
distribution
by
ages
of
females
and
males
within
a
certain
population.
This
lesson
describes
how
these
diagrams
are
constructed
and
interpreted.
It
includes
an
activity
in
which
students
use
online
data
on
Native
American
populations
from
the
United
States
Census

In this activity, students investigate the effects of automobile pollution on plant growth by making measurements on two populations of leaves, one from within 10 meters of a busy road and a population of the same species situated more than 20 meters away. They will choose a method for measuring the leaves, create a table for their data, and test their hypotheses by performing a t-test.
