Q. Select the outlier in the data set. \newline78,83,85,86,89,92,98,17078, 83, 85, 86, 89, 92, 98, 170
  1. Identify data set: Step 11: Identify the data set and look for any number that seems significantly different from the others.\newlineData set: 78,83,85,86,89,92,98,17078, 83, 85, 86, 89, 92, 98, 170\newlineLooking at the numbers, 170170 stands out as it is much higher than the rest.
  2. Calculate range and average: Step 22: Calculate the range and average of the other numbers to confirm if 170170 is an outlier.\newlineAverage of other numbers = (78+83+85+86+89+92+98)/7(78 + 83 + 85 + 86 + 89 + 92 + 98) / 7\newlineAverage = 87.2987.29 (approximately)\newlineRange of other numbers = 98−78=2098 - 78 = 20\newline170170 is much higher than 98+2098 + 20.
