... Because we want to show the impact of a training program, we need to have a pretest/post-test experimental design. In this design, we will select two groups randomly from the pool of eligible employees. At time 1 we will measure both groups on their skill level. Group A will take the training, and G ...

The immediate question which is asked by most of us is, why statistics has not been necessary all this time, and now it is required! The answer to this puz ...

It is also known as Bayesian approach because Baye’s theorem, is used to revise prior probabilities in the light of additional information. This watermark ...

... Before looking at the process for finding the probabilities under the normal curve, it is somewhat useful to look at the Empirical Rule that gives approximate values for these areas. The Empirical Rule is just an approximation and it will only be used in this section to give you an idea of what the ...

An experiment has a one-way or completely randomized design if several levels of one factor are being studied and the individuals are randomly assigned to its levels. (There is only one way to gr ...
