We will focus on some statistical methods and description of
samples. Within description of samples we will use discrete
tables and class tables (discrete and class statistics). You can
convert from class statistics to discrete statistics by using the
mean value of the intervals as the discrete value.
Statistical methods are represented by confidence intervals
and hypothesis testing for distributions. The "best" fit for the
normal distribution uses the method of least squares.
The normal distribution, kjisquare distribution and
student-t distribution are included and its possible to find
both the probability and the value of the random variable for
