    Could anyone briefly explain how Normal & Binomial Probability Distributions form the Basis of Control Charts? Just a very brief explanation would suffice.

    Control charts indicate the process Data spread that is quantified by the normal curve or upnormal ( Biased) distribution.

    Hence the normal Distributions give the spread of the data from the Centerline or Mean.

    Shape of the distribution visually gives the estimate of the process Viz.,out of control or in control process. The control chart basics then helps further to take control of the situation.

    Hope this helps you as well.

    Thanks everyone. I find the whole area of statistics quite difficult to grasp hence my request for very laymans terms. I think I’ll just have to skip this question if it comes up in an exam.
