| theoretical probability | The ratio of the number of ways an event can occur to the number of possible outcomes. |
| outcome | One possible result of a probability event. |
| sample space | The set of all possible outcomes. |
| random sampling | If the members of the sample are selected purely on the basis of chance. |
| experimental probability | An estimated probability based on the relative frequency of positive outcomes occurring during an experiment. |
| compound | Two or more simple events. |
| independent event | Two or more events in which the outcome of one event does not affect the outcome of the other event. |
| dependent event | Two or more events in which the outcome of one event does affect the outcome of the other event. |
| inference | A predictive statement or conclusion based on observation or reasoning. |
| prediction | In mathematics, we can estimate possible answers. |
| data analysis | The act of transforming data with the aim of extracting useful information and facilitating conclusions. |
| graph | Drawings or diagrams that show information, usually about how many things. |
| scatter plot | Two sets of related data are plotted as ordered pairs on the same graph. |
| trend | A long-term movement in time series data after other components have been accounted for. |
| circle graph | A type of statistical graph used to compare parts of a whole. |
| line plot | A graph that uses an X above a number on a number line each time that number occurs in a set of data. |
| histogram | A bar graph with no spaces between columns. |
| box and whisker plot | A diagram that summarizes data using the median, the upper and lower quartiles, and the extreme values. |
| stem and leaf plot | A system used to condense a set of data where the greatest place value of the data forms the stem and the next greatest place value forms the leaves. |
| tree diagram | A diagram used to show the total number of possible outcomes in a probability experiment. |
| frequency table | A table for organizing a set of data that shows the number of times each item or number appears. |
| variation | An instance of change or the rate or magnitude of change. |
| survey | A collection of data. |
| extrapolation | The process of constructing new data points outside a discrete set of known data points. |
| interpolation | Constructs new points between known points. |
| range | The difference between the greatest number and the least number in a set of data. |
| measures of central tendancy | The three measures are: mode, median, and mean. They usually fall in the middle of the distribution and tell us certain facts about it. |
| mean | The average of a set of numbers. It is found by adding all the numbers and then dividing the sum by the number of addends. |
| median | The middle number for an odd number o data, when numbers are arranged in order. For an even number of data arranged in order, the average of the two middle numbers. |
| mode | The number that occurs most often in a set of data. |
