Q. Select the outlier in the data set. \newline72,79,81,82,85,86,90,75472, 79, 81, 82, 85, 86, 90, 754
  1. Identify data set: Step 11: Identify the data set and look for numbers that stand out.\newlineData set: 72,79,81,82,85,86,90,75472, 79, 81, 82, 85, 86, 90, 754\newlineLooking at the numbers, 754754 is significantly higher than the rest.
  2. Compare numbers for outlier: Step 22: Compare 754754 with the other numbers to confirm if it's an outlier.\newlineAverage of other numbers (excluding 754754): (72+79+81+82+85+86+90)/7=575/7≈82.14(72 + 79 + 81 + 82 + 85 + 86 + 90) / 7 = 575 / 7 \approx 82.14\newline754754 is much higher than 82.1482.14, which makes it stand out as an outlier.
