Probability Distributions and Predictions (Chapter 5 in our textbook)
Statistics is the branch of mathematics that makes predictions about a population using data collected
from a sample. People who use statistics to make important decisions require a high level of confidence in the predictions. A decision based on poor statistical information can have expensive and sometimes disastrous consequences. Common sense dictates that the results from a sample may be similar to, but not exactly the same as, those for the entire population. Statisticians are interested in the probability that their predictions are representative of the population they are dealing with. If that probability is high enough, the risk of making a poor decision is minimized.

The following outline is subject to change without notice. Some lessons will take more than one day.
