Submit your work in a typed Microsoft Word document.Below are excel functions, which you can use to solve for measures of central tendency and variability. You can use the formulas too; but, they will be time consuming.EXCEL FUNCTIONSMeasures of Central TendencySuppose data are in cells A1 to A10Mean                                           =AVERAGE(A1:A10)Median                                         =MEDIAN(A1:A10)Mode                                            =MODE(A1:A10)Measures of VariabilitySuppose data are in cells A1 to A10Range                                            =MAX(A1:A10)-MIN(A1:A10)IQR                                                =QUARTILE.EXC(Array,3)-QUARTILE.EXC(Array,1)Population Variance σ2                  =VAR.P(A1:A10)Sample Variance s2                       =VAR(A1:A10) or VAR.S(A1:A10)Population Standard Deviation σ   =STDEV.P(A1:A10)Sample Standard Deviation s        =STDEV(A1:A10) or STDEV.S(A1:A10)
