Tutorial

**Experiment:** Is a situation involving chance or probability that leads to the results.

__ Outcome:__ Is the result of a single trial of an experiment.

__ Probability:__ is the measure of how likely an event is.

A __Random Sample__ is a sample from a population in which all of the individual values in the sample were selected according to their likelihood or probability in the population.

__ Sample Space:__ The concept in probability theory, which considers all the possible outcomes for an event or experiment.

__ Sample Point:__ A single possible outcome that is a member of the sample space.

__ Event:__ is any collection of outcomes in an experiment

__ Mutually Exclusive:__ Two events that cannot possibly occur together. Example: A subject cannot be both brown eyed and blue eyed, nor can they be both tall and short, but a subject could be both brown eyed and short or both blue eyed and tall.

__ All Inclusive:__ The entire population. Your entire sample falls into one category. For example, the census includes all male and female, it does not exclude any category.

__ Probability with replacement:__ a sample of the probability data that is selected, observed, and then placed back into the population sample to possibly be drawn again.

__ Probability without replacement:__ a sample of the probability data is selected, observed, but then not placed back into the population sample.
