# What does normalizing and mean centering data do?

Are there any concerns to normalizing data to be within the range 0 - 1 and mean centering the data as well?

Does it matter which comes first?

If you do one, is the other not required?

• from my understanding normalization consisted of $${x_{i} - min(x)} \over {max(x) - min(x)}$$ from that documentation, the standard scalar calculates the standard deviation and the mean and then applys it. isn't that different? – atomsmasher Jul 15 '16 at 18:49
