Describe
how
the
range
of
a
data
set
can
help
describe
its
variability.
-
correct
answer-The
range
can
help
describe
a
data
set
by
evaluating
the
whole
of
a
data
set,
showing
spread
within
a
data
set,
and
comparing
the
spread
between
similar
data
sets.
Simply
put,
it
is
the
amount
of
variation
from
the
lowest
number
to
the
highest
and
indicates
the
size
of
the
statistical
dispersion.
How
can
a
lack
of
understanding
of
the
measures
of
central
tendency
and
variability
affect
business
decisions?
Give
some
examples
to
support
your
answer.
-
correct
answer-The
measure
of
central
tendency
give
you
a
picture
of
what
to
expect
in
a
situation.
My
example:
a
basketball
players
"average"
is
the
number
of
points
that
they
usually
score.
In
a
business
you
make
decisions
on
what
you
expect
to
happen.
If
you
know
the
measure
of
center
it
can
help
you
make
better
decisions.
