Biased Sample		Median=The middle number when the numbers are written in order.
Dependent Events		Mode=The number(s) repeated most often.
Independent Events		A part of the population
Combination		Interquartile Range=Upper Q-Lower Q.
Permutation		Every event is listed outwards in a tree until every event has been listed.
Measures of Central Tendency		A question that influences a specific answer.
Stratified Random Sample		Mean=Average
Survey		Only members of the group who are easily acceptable are selected.
Quartiles		In a set of data, it is the average amount all of the data is away from the mean.
Biased Question		Add AND Subtract
Quartiles		A sample that does not represent all the characteristics of a sample.
Population		Lower Q.=median of bottom half of data.
Independent Events		The chance of an event occuring.
Representative Sample		A rule is used to select members of the population.
Range		The number of ways an event can occur when you are not using all objects.
Tree Diagram		Multiply
Expected Value		The probability of more than one event with the workd "AND,BOTH,or IN A ROW".
Counting Principle		The number of ways an event can occur.
Permutation		The number of ways an event can occur when you are not using all objects.
Measures of Central Tendency		Add
Mutually Exclusive Events		A median of a set of data; normally split up into a lower and upper.
Factorial		The probability of more than one event with the 'OR".
Sample		To multiply the number all the way down until it reaches 1.
Self-Selected Sample		Members of a population choose to be part of the sample.
Systematic Sample		Multiply
Random Sample		Every member of the population has an equal chance of being selected.
Quartiles		Thehighest number in a set of data minus thelowest number in a set of data.
Dependent Events		When probability of an event is multiplied by it's worth to determine a postivie or negative outcome.
Combination		Multiply
Counting Principle		The probability of more than one event with the 'OR".
Measures of Central Tendency		Order Matters
Mutually Exclusive Events		The entire group you want information about.
Overlapping Events		Order does NOT matter.
Quartiles		The population is divided into distinct groups.Members selected randomly.
Probability		The probability of more than one event with the word "AND,BOTH,or IN A ROW".
Convenience Sample		Uper Q.=median of upper half of data.
Overlapping Events		A sample that accurately reflects the characteristics of a population.
Mean Absolute Deviation		Study of one or more characteristics of a group.
