Normal Probability Distribution
The focus of the section on the Normal Probability
Distribution is to identify
situations that give rise to Normal distributions by demonstrating
an ability to
understand the properties of the Normal distribution, use these properties
to
solve problems and make probability statements about Normal distributions.
The Normal Probability Distribution is a fundamental
building block for most
elementary parametric Statistics, important applications are
1. it is the theoretical distribution of
random error when the scale is
continuous, for example, if every student
in your school was given
a ten centimetre rule to measure the length
of the gym, the
resulting distribution of their measurements
would follow a Normal
distribution.
2. it is the theoretical distribution for the means of randomly
drawn
large samples, for example, if everyone
in the class rolled a dice
50 times and was asked to compute the
mean of their results,
the distribution of the means from
the class would follow a Normal
distribution.
