For non specialized person, what is standard deviation - as simple as possible -?
Can standard deviation tell us anything about the shape of the data distribution?
Yes, it can! The standard deviation can tell us whether the data is tightly clustered around the mean or spread out, and whether the distribution is symmetrical or skewed. A high standard deviation suggests that the data is widely spread, while a low standard deviation suggests that the data is tightly clustered around the mean. And if the distribution is symmetrical, the standard deviation will be larger if the distribution is wider, or smaller if the distribution is narrower.
