| Question | Answer |
|---|---|
| Multiplication counting principle | If 1 event can occur in m ways and another can occur in n ways, the number of ways both can occur together is m x n. |
| Addition counting principle | If the possibilities being counted can be divided into groups with no possibilities in common, the total number of possibilities is the sum. |
| Permutation | An arrangement of objects in which order is important. |
| Combination | A selection of objects in which order is not important. |
| Compound event | Combines 2 or more events, using the word and or the word or. |
| Mutually exclusive events | No common outcomes. |
| Overlapping events | At least one common outcome. |
| Independent events | One event has no effect on the other. |
| Dependent events | One event affects the outcome of the other. |
| Conditional probability | If events are dependent, the probability the second one will occur, given the results of the first one. |
| Expected value | The sum of the probabilities of an event multiplied by the corresponding outcomes. |
| Survey | Study of one or more characteristics of a group. |
| Population | The entire group you want information about. |
| Random sample | Every population member has an equal chance of being selected. |
| Stratified random sample | Population is divided into groups, and members are selected at random from each group. |
| Systematic sample | A rule (such as every 3rd one) is used to select members of the population. |
| Convenience sample | Easily accessible members of the population are selected. |
| Self-selected sample | Members select themselves by volunteering. |
| Representative sample | Sample accurately relects the characteristics of the population. |
| Biased sample | Sample doesn't represent the population. |
| Biased question | Encourages a particular response. |
| Measure of central tendency | Indicator of the middle of the data. |
| Measure of dispersion | Indicator of how much the data is spread. |
| Mean absolute deviation | Average distance from the mean. |
| Quartile | Median of an ordered data set |
| Upper quartile | Median of the upper half of an ordered data set. |
