Lec. 11 – The Normal Distribution
Differences among these plots?
How to “standardize” (shift and stretch the Gaussian to a mean of 0 and a std. dev. of 1):
Note that “any linear function of the normal variable X, aX+b, where a and b are constants, also has a normal distribution with mean = am+b, and std. dev.= as
* See also “Comparing Normal Populations” in Davis, pp. 55-58.
Standardization and the use of tables…
Standard cumulative percentage table for a normally-distributed population
Table of percentage points for a normally-distributed population
Standardization to calculate exceedence
But, we don’t want to be tethered to these tables…
Write a MATLAB code that calculates the values of the tables and displays them graphically (i.e. plot up the gaussian p.d.f. and its cumulative brother).
