In skewed data, the mean is influenced by extreme values and tends to be pulled in the direction of the skew. For instance, in a right-skewed distribution, the mean will be greater than the median, and in a left-skewed distribution, it will be less than the median. Thus, the mean can indeed differ significantly from the median depending on the distribution's shape! To prevent confusion while interpreting skewed data, it’s vital to visualize the distribution using graphs like histograms or box plots. This helps to grasp the extent of the skewness and understand how the mean and median relate to each other. Remember, in skewed datasets, the median usually provides a better measure of central tendency!
