which of the following is used to identify outliers in a set of data?\n1.5(iqr)\n1.5(range)\n2(mean)\n2(median)

Answer

Answer:

  1. 1.5(IQR)

Explanation:

Step1: Recall outlier rule

The common rule for identifying outliers in a data - set is based on the inter - quartile range (IQR).

Step2: State the rule

Outliers are typically identified as values that are less than (Q_1 - 1.5\times IQR) or greater than (Q_3+1.5\times IQR), where (Q_1) is the first quartile, (Q_3) is the third quartile, and (IQR = Q_3 - Q_1). So, 1.5(IQR) is used to identify outliers.
