1 point Which of the following is the correct procedure to determine the lower and upper thresholds for finding the outliers of a data set? Lower Threshold = Q1 + (1.5 x IQR) and Upper Threshold = Q3 -(1.5 x IQR) Lower Threshold = Q1 and Upper Threshold = Q3 Lower Threshold = Q1 - IQR and Upper Threshold = Q3 + 1OR Lower Threshold = Q1 - (1.5 x 1QR) and Upper Threshold = Q3 + (1.5 x IQR)
