Variability “from the
mean”
Deviation. It is the sum of
absolute values of the
MM2d1 b.
differences of observations
from mean; Level B concept,
Early Level C
Deviation. It is the average of
the distances of the
MM2D4
observations from the mean –
a Level B concept, early
Level C
Level A – fair share
interpretation of the mean;
variability from the fair
M6D1 d.
share is measured by
"number of steps" to the
fair share or to “level off” the
stack of cubes
Relationship between # of
steps to level off and the
MM2D1 b.
number of steps (from level
A)
Level B – interpretation of
MM2D1 c.
mean = balance point
Level C – How do we take a
sample mean and make an
M7D1 e.
population mean? “How
close can we expect our
sample mean to be to the
population mean?”
Level C – measure
variability by Standard
Deviation (differs from
