| numbers that describe a set of data | statistics |
| the chance of an event occuring | probability |
| if a 2 step situation or experiment has blank ways to do the first step and blank ways to do the second step then the total number of possible outcomes for both steps is m*n | fundamental counting principal |
| a sample in which every individual in the population has the same chance of being included | random sample |
| a sample for which the results of the sample can be considered the same as the results from the entire population | representative sample |
| the differences between what the responses of a sample are and what the actual responses from the entire population would be | bias |
| two or more events with no outcomes in common | disjoint events |
| improbability, an event that is not effected by another event | independent events |
| an event that is effected by the outcome of another event | dependent event |
| a number or numbers that are at one or the other end of a set of data arranged in order where there is a gap between the end of numbers and the rest of the data | outlier |
| something that has different outcomes, a letter or a symbol that represents a number in an algebraic expression | variable |
| the x-axis in a coordinate system, it is a number line that locates points to the left or to the right of the origin | horizontal axis |
| the y-axis in a coordinate system, it is a number line that locates points to up or down from the origin | vertical axis |
| the set of positive whole numbers and their opposites (negative numbers) and zero | integers |
| per hundred, ratio of a number to one hundred | percent |
| the order in which operations in an expression to be evaluated are carried out. Do the operation in parentheses first, next evaluate exponents, then multiple and divide from left to right, and finally add and subtract from left to right | order of operations |
| factoring a number into its prime factors only | prime factorization |
| the mean, median, and mode | measures of central tendency |
| An event that consists of the outcome of two or more events | compound event |
| fractions that show different numbers with the same value | equivalent fractions |
