2 Choosing the Best Measure of Center Find the mean, median, and mode of the sneaker prices. Which measure best represents the data? Mean: 20+31 +122 +48 +37 +20 +45 + 65 8 = 388 8 , or 48.5 Median: 20, 20, 31, 37, 45, 48, 65, 122 Order from least to greatest. 37+45 82 or 41 2 2 Mode: 20, 20, 31, 37, 45, 48, 65, 122 The value 20 occurs most often.

The mode is less than most of the data, and the mean is greater than most of the data. On Your Own Find the mean, median, and mode of the data. Choose the measure that best represents the data. Explain your reasoning. 3. 1, 93, 46, 48, 34, 194, 67, 55 4. 96, 150, 102, 87, 150, 75 3 An outlier is a data value that is much greater or much less than the other values. Removing an Outlier Identify the outlier in Example 2. Find the mean, median, and mode without the outlier. Which measure does the outlier affect the most? The price of $122 is much greater than any other price. So, it is the outlier. Mean Median Mode 2 Choosing the Best Measure of Center Find the mean, median, and mode of the sneaker prices.
