Q. Select the outlier in the data set.\newline9,56,62,64,69,72,74,849, 56, 62, 64, 69, 72, 74, 84
  1. Identify Data Set: Step 11: Identify the data set and the need to find the outlier.\newlineData set: 9,56,62,64,69,72,74,849, 56, 62, 64, 69, 72, 74, 84.\newlineWe need to find the number which is significantly different from the others.
  2. Calculate Range and Median: Step 22: Calculate the range and median to observe any significant differences.\newlineRange = Maximum value - Minimum value\newlineRange = 849=7584 - 9 = 75\newlineMedian (middle value of sorted data) = (69+72)/2=70.5(69 + 72) / 2 = 70.5\newlineCheck if any number is far from the median and the rest of the data.
  3. Compare Numbers to Median: Step 33: Compare each number to the median and the rest of the data.\newlineMost numbers are clustered around the median (70.570.5), except for 99, which is much lower than the next closest number (5656).\newlineThis suggests 99 is an outlier.
