Difficult: Medium <br> Category: Problem Solving and Data Analysis/ Statistics and Probability. <br> Strategic Advice: Knowing when the mean and median of a data set are equal is the key to answering a question like this. <br> Getting to the Answers: The mean of a data set is approximately equal to the median when the data has a symmetrical distribution. In this scenario, the mean and median are not equal, which indicates that the data distribution is asymmetric. The difference between them is fairly large (compared to the values themselves). which could be explained by the presence of outliers (values that are significantly smaller or larger than the other values in the data). Outliers affect the mean of a data set but not the median. Because the mean is lower than the median, the outliers must also be on the low side, which means you can reasonably conclude conclude that a few areas in the study had gas prices that were much than those elsewhere in ths state. Chice (A) is correct.
