Normal Curve

Summary
The normal model is roughly symmetrical and unimodal.

N(μ,σ)

μ = .6

σ = .3775

T-score
T= 3.154

(y - μ) shifts data: adding/subtracting to all data increases/decreases the median and mean (does not change standard deviation, range, or IQR)

σ rescales data: multiplying/dividing to all data increases/decreases median, mean, standard deviation, range, and IQR by the same multiple
