A skewed distribution indicates that there are extreme values that are pulling the mean away from the center of the distribution, which makes it an unreliable measure of central tendency. The mode is not a suitable measure for skewed distributions because it may not be a representative value for the entire distribution. The range only indicates the spread of the data and does not provide any information about the center. The standard deviation measures the variability of the data around the mean, but it is not a measure of central tendency. The median, on the other hand, is a reliable measure of central tendency for skewed distributions because it represents the middle value of the entire data set, regardless of the presence of outliers or extreme values.
