Noise in data is meaningless data or unexplained variation in data which might be due to instrument errors, corruption or other issues. Noise disguises and/or distorts the underlying data which make it harder to analyse, just as noisy environments make it more difficult to hear the sound on which you wish to focus.

Normal distribution

The normal distribution is used to model some continuous variables. It is a symmetrical bell shaped curve that is completely determined by two parameters. They are the distribution (or population) mean, μ, and the standard deviation, σ.

Numerical Variable

Refers to a variable whose possible values are numbers (as opposed to categories).
