Beyond the Answer
To identify outliers in the dataset, we use the Interquartile Range (IQR). First, we need to find the first (Q1) and third quartiles (Q3). 1. Sort the data: \( 73, 74, 75, 83, 85, 86, 88, 91, 92, 92, 195 \) 2. Find Q1 (the median of the first half): \( Q1 = 83 \) 3. Find Q3 (the median of the second half): \( Q3 = 92 \) 4. Calculate IQR: \( IQR = Q3 - Q1 = 92 - 83 = 9 \) Now, we determine the lower and upper bounds: - Lower bound: \( Q1 - 1.5 \times IQR = 83 - 13.5 = 69.5 \) - Upper bound: \( Q3 + 1.5 \times IQR = 92 + 13.5 = 105.5 \) Any score below 69.5 or above 105.5 is an outlier. In this dataset, \( 195 \) is the only score that falls outside this range. So, the outlier is: **195**.
