Select the outlier in the data set. 78, 83, 85, 86, 89, 92, 98, 170

Identify data set: Step 1: Identify the data set and look for any number that seems significantly different from the others. Data set: 78, 83, 85, 86, 89, 92, 98, 170 Looking at the numbers, 170 stands out as it is much higher than the rest.Calculate range and average: Step 2: Calculate the range and average of the other numbers to confirm if 170 is an outlier. Average of other numbers = (78 + 83 + 85 + 86 + 89 + 92 + 98) / 7 Average = 87.29 (approximately) Range of other numbers = 98 - 78 = 20 170 is much higher than 98 + 20.
