The leaves for one set of data are on one side of the stem, and the leaves for the other set of data are on the other side. box-and-whisker plotjbox-and-whisker plot:ÖA diagram that divides a set of data into four parts using the median and quartiles.  combinationGcombination:ÖAn arrangement or listing in which order is not important. dependent eventsodependent events:ÖTwo or more events in which the outcome of one event affects the outcome of the other events. experimental probability‹experimental probability:ÖThe ratio of the number of positive outcomes to the total number of events or trials in a probability experiment. Fundamental Counting Principle³Fundamental Counting Principle:ÖIf an event M can occur in m ways and is followed by an event N that can occur in n ways, then event M followed by event N can occur inÖm n ways.  histogramhistogram:ÖA bar graph in which the data are organized into equal intervals. The height of the bar represents the frequency in that interval. independent eventsyindependent events:ÖTwo or more events in which the outcome of one event does not affect the outcome of the other events.  interquartile range~interquartile range:ÖThe difference between the upper and lower quartiles representing the middle half of the data in the set.  leafPleaf:ÖA digit written to the right of the vertical line in a stem-and-leaf plot.  lower quartileMlower quartile:ÖDivides the lower half of a set of data into two equal parts.  measure of variationYmeasure of variation:ÖA measure that describes the spread of the values in a set of data.  mutually exclusive eventsSmutually exclusive events:ÖTwo or more events whose outcomes can never be the same. outcomekoutcome:ÖOne possible result of a probability event.ÖExample:Ö4 is an outcome when a number cube is rolled. outlieroutlier:ÖAny element of a set of data that is at least 1.5 interquartile ranges less than the lower quartile or greater than the upper quartile.  permutationYpermutation:ÖAn arrangement or listing of a group of objects in which order is important.  probabilityÅprobability:ÖThe ratio of the number of favorable outcomes for an event to the number of possible outcomes of the event. P(a) = (number of favorable outcomes) / (total number of possible outcomes).  quartilesBquartiles:ÖValues that divide a set of data into four equal parts. range of a data setfrange of a data set:ÖThe difference between the greatest number and the least number in a set of data.  sample space=sample space:ÖThe list of all possible outcomes for an event. stemOstem:ÖA digit written to the left of the vertical line in a stem-and-leaf plot. stem-and-leaf plotŒstem-and-leaf plot:ÖA display of data in which each piece of the data is separated into two numbers that are used to form a stem and a leaf. theoretical probabilityptheoretical probability:ÖThe ratio of the number of favorable outcomes to the total number of possible outcomes.  tree diagramWtree diagram:ÖA diagram used to show the total number of possible outcomes of an event. upper quartile6upper quartile:ÖThe median of the upper half of a set.é·
