Question

question help: a data value must be lower than to be considered a low outlier (the lower limit). a data value must be higher than to be considered a high outlier (the upper limit). list any data values flagged as outliers. list your answers, separated with commas. q1 = 60 q3 = 140 iqr = 80

Explanation:

Step1: Recall outlier formula

For high - outliers, the upper limit is $Q_3 + 1.5\times IQR$. For low - outliers, the lower limit is $Q_1-1.5\times IQR$.

Step2: Calculate upper limit for high outliers

Given $Q_3 = 140$ and $IQR = 80$. Then $Q_3+1.5\times IQR=140 + 1.5\times80=140 + 120=260$.

Step3: Calculate lower limit for low outliers

Given $Q_1 = 60$ and $IQR = 80$. Then $Q_1 - 1.5\times IQR=60-1.5\times80=60 - 120=- 60$.

Answer:

Low outliers: values less than - 60; High outliers: values greater than 260
