 Standardization Is the process of converting an x value from a normal distribution into a z score (units oflength sigma from the center mu) Z score formula z=(x-mu)/sigma Z score reports how many std.dev an x value lies from the mean and in which direction. Applet results 1.Decreasing mu increasing area to left of z 2.Increase x increase in area to left of z score 3.sigma increase widens the graph Comparing Areas of Normal vs Std.Normal Curve 1. Area to right of z score=Area to right of x value 2.Area to left of z score=Area to left of x value Find Area Process 1.Given x--Standardize--Use Std.Norm Table--Area 2.Given Area--Use std.norm table--find z--convert to x Note See practice questions for understanding problems
