  6. Another Method of Finding the Mean and Median Given the data set {13, 3, 10, 9, 7, 10, 12, 8, 6, 3, 9, 6, 11, 5, 9, 13, 8, 7, 7}find the mean, median and mode. Enter the data into a list. • Press the STAT button • Choose EDIT • Type your data http://mathbits.com/MathBits/TISection/Statistics1/MeanModeMedian.htm

  7. Press STAT.  • Arrow to the right to CALC.   • Choose option #1: 1-Var Stats. • PressENTER. • Arrow up and down the screen. http://mathbits.com/MathBits/TISection/Statistics1/MeanModeMedian.htm

  8. Find the Mode • STAT, #2 SortA(, and specify L1 • Look at the list (STAT, #1 EDIT). Examine the data to see which value(s) appear(s) most often. • The mode for this data set is 7 and 9.  Each of these values appears 3 times in the data set. http://mathbits.com/MathBits/TISection/Statistics1/MeanModeMedian.htm
