| bar graph | to compare different categories of data |
| circle graph | to show data as parts of a whole set of data |
| line graph | to show the change in data over time |
| line plot | frequency shown by placing an X above |
| mean | calculated by taking the sum of all the data & dividing it by the # of data |
| median | you order the data points in order, then find the one in the middle |
| mode | the value that occurs most frequently |
| histograms | a bar graph in which the data is orginized into equal intervals or measurment class |
| frequency | the number of values within each class |
| measures of variation | they describe the spread od the values in a set of data |
| quartiles | they seperate the data into four equal subsets, each containing one fourth of the data |
| interquartile range | the difference between the upper and lower quartiles |
| five-number summary | consists of the minimum, maximum, Q1, median, Q3 |
| probabilty | the likehood of an event happening |
| odds | a ratio that conpares the # of ways an event can occur (successes) to the # of ways it cannot occur (failures) |
| odds against | a ratio of failure to successes |
| fundamental counting principle | if an event M can occur in M ways and is followed by an event N that can occur in N ways, then the event M followed by the event N can occur in MN ways |
| permutations | an arragement or listing in which an order or placement is important |
| combinations | a listing in which order is NOT important |
| simple event | single event |
| compound event | consists of two or more simple events |
| independent events | if the outcome of one simple event does not affect the outcome of another |
| dependent events | when the outcome of one event affects the outcome of another event |
| mutually exsclusive events | events that cannot happen at the same time |
| inclusive events | two events that can happen at the same time |
