... To motivate the Central Limit Theorem (CLT), assume we have a population of arbitrary shape (right skewed, left skewed, flat, bimodal, etc) with mean and standard deviation . Take 1000 random samples each of size n from the population and for each compute the sample mean, the sample median and th ...

... From the definition of reliability given earlier (10), we note that the reliability of the combined measure is p2 / (p2 + 0.5*err2). However, from previous expressions we can see that either measure alone has a reliability of p2 / (p2 + err2). It is thus apparent that the combined measure is m ...

Standard Deviation
... Calculating mean and standard deviation on the TI-83: 1. First we have to enter the data. Hit the STAT button and you will see the options EDIT, CALC and TESTS atop the screen. Use the left and right arrows (if necessary) to move the cursor to EDIT, then select 1:Edit... 2. Now you will see a table ...
