Census- an official count or survey of a population, typically recording various details of individuals.

Complementary Events- are two outcomes of an event that are the only two possible outcomes.

Compound Events- involves finding the probability of more than one event occurring at the same time

Data- is a collection of facts, such as numbers, words, measurements, observations or just descriptions of things.

Deviation From The Mean- a measure of difference between the observed value of a variable and some other value, often that variable's mean.

Dot Plot- also called a dot chart, is a type of simple histogram-like chart used in statistics for relatively small data sets where values fall into a number of discrete bins.

Equally Likely- events that have the same theoretical probability (or likelihood) of occurring.

Event- A set of possible outcomes resulting from a particular experiment. For example, a possible event when a single six-sided die is rolled is {5, 6}.

Experiment- is any activity with an observable result. Tossing a coin, rolling a die or choosing a card are all considered experiments.

Experimental Propability- based on an experiment written as a ratio comparing the number of times the event occurred to the number of trials.

Mean-  is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. 

Mean Absolute Deviation- a data set is the average distance between each data value and the mean.

Median- the "middle" value in the list of numbers. To find the median, your numbers have to be listed in numerical order from smallest to largest, so you may have to rewrite your list before you can find the median.

Mode-  The number which appears most often in a set of numbers.  

Example: in {6, 3, 9, 6, 6, 5, 9, 3}

Outcome- a result of an event that depends on probability, and any event can have more than one possible outcome.

Parameter- a quantity that influences the output or behavior of a mathematical object but is viewed as being held constant.

Population-  in statistics and other areas of mathematical, is a discrete group of people, animals or things that can be identified by at least one common characteristic for the purposes of data collection and analysis. 

Probability-  tells you the likelihood of an event happening. The lower the probability, the less likely it is to happen

Probability Model- a mathematical representation of a random phenomenon. It is define by its sample space, events within the sample space, and probabilities associated with each event.
