(3) Median: The median is the middle value in a sorted dataset. It is not related to the square root of squared differences. (4) Standard Deviation: The standard deviation is the positive square root of the variance. It represents the spread of data around the mean. Therefore, (4) Standard Deviation is the positive square root of the average of the squared difference of each value from the mean.
