6-6I Normal Distribution CurveThe normal distribution curve is graphed using the normaldistribution function.XList specifies the list where the data is input, while Freqspecifies the list where the data frequency is input. 1 isspecified for Freq when frequency is not specified.I Broken Line GraphLines connect center points of a histogram bar.XList specifies the list where the data is input, while Freq specifies the list where the datafrequency is input. 1 is specified for Freq when frequency is not specified.U(DRAW)The display screen appears as shown above before the graph is drawn. At this point, you canchange the Start and Width values.I Displaying the Calculation Results of a Drawn Single-Variable GraphSingle-variable statistics can be expressed as both graphsand parameter values. When these graphs are displayed,the single-variable calculation results appear as shown tothe right when you press (1VAR).• Use A to scroll the list so you can view the items that run off the bottom of the screen.The following describes the meaning of each of the parameters.Q1 ................first quartileMed ..............medianQ3 ................third quartilemaxX............maximumMod ..............modeMod:n ..........number of data mode itemsMod:F ..........data mode frequency¯x ..................mean3x ................sum3x2 ...............sum of squaresSx .................population standarddeviationsx .................sample standarddeviationn ..................number of data itemsminX.............minimum
