Answer 1

In data science, there are two broadly used normalization types:

1) Where we try to shift the data so that there sum is a particular value, usually 1 (https://stats.stackexchange.com/questions/62353/what-does-it-mean-to-use-a-normalizing-factor-to-sum-to-unity)

2) Normalize data to fit it within a certain range (usually, 0 to 1): https://stats.stackexchange.com/questions/70801/how-to-normalize-data-to-0-1-range
