Question

Here is a sample data set (n = 48) that is nearly normal (as can be seen in the histogram provided after the data set . 27.3 33.2 33.8 343 34.6 35.6 38 38.8 39 39.1 39.340.340.841.741.7 42.3 42.3 42.3 43 43.2 44.2 45 45.4 45.6 45.845.846.4474747.247.4 49.9 50.1 50.4 51.5 51.5 51.7 52.6 53.3 54.2 54.8 57.4 58.2 58.259.160.6 61.4 63.6 10 4 25 30 35 40 45 50 55 60 data How many outliers are in this data set? ans For this data set, classify anything beyond 2 standard deviations from the mean as a potential outlier.

Explanation / Answer

The statistical software output for this problem is:

Summary statistics:

Hence,

Range of usual values = (46.16 - 2*8.256, 46.16 + 2*8.256) = (29.65, 62.67)

So outliers are 27.3 and 63.6

Number of outliers = 2

Column Mean Std. dev. Data 46.164583 8.2558423
