I was studying in my math textbook about these two methods to measure dispersion and variability in data. I was able to understand mean deviation that it's the average by how much a quantity deviates from mean but I was unable to understand standard deviation. Also, as standard deviation squares deviation it makes big deviation bigger. So, please help to understand why it's preferred over mean deviation.
