198 Chapter 14: Statistics Whiskers are the lines protruding from the sides of the box. second plots in the middle. When three are plotted, the first one plots at the top, the second in the middle, and the third at the bottom. ¬ HIST (histogram) plots one-variable data. The xScl window variable value determines the width of each bar, beginning at xMin. ZDATA (GRAPH ZOOM menu) adjusts xMin, xMax, yMin, and yMax to include all values, and also adjusts xScl. (xMax N xMin) à xScl  47 must be true. A value that occurs on the edge of a bar is counted in the bar to the right. For the example: xStat={1 2 2 2 3 8 9 5 6 6 7 7 4 4 9 9 9} Window variable values: xMin=0 yMin=0 xMax=10 yMax=5 ° BOX (regular box plot) plots one-variable data. The whiskers on the plot extend from the minimum data point in the set (xMin) to the first quartile (Q1) and from the third quartile (Q3) to the maximum point (xMax). The box is defined by Q1, Med (median), and Q3. For the example: xStat={1 2 2 2.5 3 3.3 4 4 2 6 9} Window variable values are set by selecting ZDATA from the GRAPH ZOOM menu. Box plots are plotted with respect to xMin and xMax, but ignore yMin and yMax. When two box plots are plotted, the first one plots at the top of the screen and the second plots in the
