Normal
Sometimes, rather than finding the probability of our random
variable being between two values, we prefer to find the actual
raw score that is associated to a certain percentage.

7.1b- Introduction to the Normal Distribution
In the previous lecture, we looked at the uniform distribution,
which was a probability density function for having an equal
probability for any interval being selected.
However, not all continuous random vari
6.3- The Poisson Distribution
Another very common discrete distribution is called the
poisson distribution. The Poisson distribution counts the
number of occurrences as a success (X) in some interval
(usually time based).
Lets look at a common example.

7.2a- Finding Probabilities using the Normal Distribution
If we have a random variable that we think may have a normal
distribution (or is approximately normally distributed), the area
underneath the normal curve represents the proportion of the

Review of Sampling Distributions
With all weve learned thus far, it can become very confusing trying to identify
which sampling distribution to reference, what the different notations mean,
and what is going in these z-formulas.
