    What is Z-curve? How it is different from normal distribution curve for six sigma?

    #42133

    Ravi,
    The z curve refers to the standard normal distribution. That is, a normal distribution with mean = zero and std dev =1.0. It is this distibution for which areas under the curve are tabled in most statistics textbooks.
    The “normal curve for six sigma” in your question is a theoretical curve used to explain concepts and it is the same as the z curve.
