IQR= Lower boundary: Upper boundary: X Outliers: X (c) Calculate a lower boundary using Q₁-1.5 IQR. Calculate an upper boundary using Q3 +1.5 IQR. (Note that 1.5 IQR means 1.5 times the IQR.). X DO.... (d) Any values less than the lower boundary or greater than the upper boundary are considered outliers. Identify al the outliers of the data set. If there is more than one outlier, separate them with commas. If there are no outliers, click "None". X 2/5 S None Español S
