Consider the scatter plot above, which shows data for students on a backpacking trip. (Each point represents a student.)Aug 21, 2023 · However, to calculate the quartiles, we need to know the minimum, maximum, and median, so in fact, we need all of them. With that taken care of, we're finally ready to define outliers formally. 💡 An outlier is an entry x which satisfies one of the below inequalities: x < Q1 − 1.5 × IQR or x > Q3 + 1.5 × IQR. Next, we see that 1.5 x IQR = 15. This means that the inner fences are at 50 – 15 = 35 and 60 + 15 = 75. This is 1.5 x IQR less than the first quartile, and more than the third quartile. We now calculate 3 x IQR and see that this is 3 x 10 = 30. The outer fences are 3 x IQR more extreme that the first and third quartiles.Choose Stat > Basic Statistics > Outlier Test. ; In Variables, enter BreakStrength. ; Click Options. ; From What do you want to determine?
