The height of the bar represents the frequency in that interval. leafPleaf:A digit written to the right of the vertical line in a stem-and-leaf plot.  line graphIline graph:Numerical data displayed to show trends or changes over time.   line plotline plot:A number line labeled with a scale to include all the data with a mark placed above a data point each time it occurs.  meanamean:The sum of the numbers in a set of data divided by the number of pieces of data in the set.  measure of central tendency]measure of central tendency:A number or piece of data that represents the whole 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. 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.  random sample^random sample:Each item or person in the population is as likely to be chosen as any other.  range of a data setfrange of a data set:The difference between the greatest number and the least number in a set of data.  scatter plot !Rscatter plot:A graph that shows the general relationship between two sets of data  statisticsGstatistics:The study of collecting, organizing, and interpreting data. stemOstem: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. voluntary response sampleUvoluntary response sample:A sample that involves only those who want to participate.8`HH>8p <<    0 x x 00xx0````<<``@@(<(<(>z
