These measures include the mean, median, and mode.   median«median:ÖThe 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:ÖThe number(s) or item(s) that appear most often in a set of data. negative number3negative number:ÖAny number that is less than zero.  opposites@opposites:ÖEvery positive rational number and its negative pair. 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. positive number6positive number:ÖAny number that is greater than zero. range of a data setfrange of a data set:ÖThe difference between the greatest number and the least number in a set of data. 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.  vertical axis[vertical axis:ÖThe axis on which the scale and interval are shown in a bar or line graph. n=
