The value on the left side of the figure represents one set of data and that on the right side represents other set of data.  biased sample]biased sample:A sample in which one or more parts of the population are favored over others. box-and-whisker plotjbox-and-whisker plot:A diagram that divides a set of data into four parts using the median and quartiles.  combinationsHcombinations:An arrangement or listing in which order is not important. compound eventsFcompound events:An event which consists of two or more simple events. convenience sample_convenience sample:A sample which includes members of the population that are easily accessed. dependent events odependent events:Two or more events in which the outcome of one event affects the outcome of the other events. experimental probabilityexperimental probability:The ratio of the number of positive outcomes to the total number of events or trials in a probability experiment.  Fundamental Counting Principle 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 event M followed by event N can occur in m x n ways.   histogram!histogram:A bar graph in which the data are organized into equal intervals. The height of the bar represents the frequency in that interval.The figure aside is the Histogram of Points scored per Basketball Game.  independent events{independent events:Two or more events in which the outcome of one event does not affect the outcome of the other event(s).  interquartile range~interquartile range:The difference between the upper and lower quartiles representing the middle half of the data in the set.  leavesRleaves:A digit written to the right of the vertical line in a stem-and-leaf-plot. lower quartileMlower quartile:Divides the lower half of a set of data into two equal parts. meanamean:The sum of the numbers in a set of data divided by the number of pieces of data in the set. measures of central tendency^measures of central tendency:A number or piece of data that represents the whole set of data. measures of variationZmeasures of variation:A measure that describes the spread of the values in a set of data. medianmedian:The middle number in a set of data when the data are arranged in numerical order. If the data has an even number, the median is the mean of the two middle numbers. modeGmode:The number(s) or item(s) that appear most often in a set of data. mutually exclusive events Smutually exclusive events:Two or more events whose outcomes can never be the same.  odds againstodds against:The ratio that compares the number of ways the event cannot occur to the number of ways that the event can occur. odds in favor odds in favor:The ratio that compares the number of ways the event can occur to the number of ways that the event cannot occur. outcomesmoutcomes:One possible result of a probability event. Example: 4 is an outcome when a number cube is rolled. outlieroutlier:Any 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.  permutationsZpermutations:An arrangement or listing of a group of objects in which order is important.  population Vpopulation:A large group of data from which a sample of statistical data is selected.  probabilityf!}probability:The ratio of the number of favorable outcomes for an event to the number of possible outcomes of the event.   quartilesBquartiles:Values that divide a set of data into four equal parts. randomLrandom:Outcomes occur at random if each outcome is equally likely to occur. rangeXrange:The difference between the greatest number and the least number in a set of data. sampleHsample:Some portion of a larger group selected to represent that group.   sample space=sample space:The list of all possible outcomes for an event.!  simple eventGsimple event:It is defined as one outcomeor a collection of outcomes." simple random sampleusimple random sample:It is defined as each item or person in a population which is likely to be chosen as any other.# stemsPstems:A digit written to the left of the vertical line in a stem-and-leaf plot.$ stem-and-leaf plotstem-and-leaf plot:A 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.% stratified random samplestratified random sample:A sample in which the population is first divided into similar, nonoverlapping groups; a simple random sample is then selected from each group.& systematic random samplesystematic random sample:A sample in which the items in the sample are selected according to a specified time or item interval.' theoretical probabilityptheoretical probability:The ratio of the number of favorable outcomes to the total number of possible outcomes.(  tree diagramsXtree diagrams:A diagram used to show the total number of possible outcomes of an event.) unbiased sampleaunbiased sample:A sample that is selected so that it is representative of the entire population.* upper quartile6upper quartile:The median of the upper half of a set.+ voluntary response sample Uvoluntary response sample:A sample that involves only those who want to participate.`R[$28( !!#@@"EBbR8`$ U+U ()UU$T#U81*)U U T )U|+W)UUZT8 U$UZTU1UZTX UTUZVD!UU`89UZVUU`jUZV>UVUU` p>*@ H@  *@`"@ 0́pJ "@Jp2 *@`"@8` (c%!T*rTTR*" RQ%!"?#BJR(#cJP!#0sJ(!JB$(BsHBc(Jc$(
