Quick Update 6 February 2014

The following have been added to the website:

The description of Fleiss’ kappa has been updated to add the standard error and confidence intervals.

A new webpage on Runs has been added. This page shows how to calculate the probability of getting at least k heads in a row in n tosses and similar problems. The approach uses recursion and can be done in Excel.

A simple example of the Binomial Distribution and Random Walks is given which shows how to determine the expected deviation of the total number of heads in n tosses from the expected value of n/2. The result is a bit surprising.

I hope that you find these new additions useful and interesting.
