The sign S k gives … WebIn a perfectly symmetrical distribution, the mean, median, and mode will all be the same value. The mean is affected by outliers or extreme values in the dataset, while the median and mode are not. If you try to find measures of central tendency for grouped data in a positively skewed distribution, the mean will be greater than the median, whereas, in a …
