What is the formula for converting a normal distribution into a standard normal distribution?
Any point (x) from a normal distribution can be converted to the standard normal distribution (z) with the formula z = (x-mean) / standard deviation. z for any particular x value shows how many standard deviations x is away from the mean for all x values.
How do you convert SD to z-score?
How do you find the z-score with mean and standard deviation? If you know the mean and standard deviation, you can find the z-score using the formula z = (x - μ) / σ where x is your data point, μ is the mean, and σ is the standard deviation.
How do you convert probability to z-score?
The following formula converts an X value into a Z score, also called a standardized score: where μ is the mean and σ is the standard deviation of the variable X. In order to compute P(X < 30) we convert the X=30 to its corresponding Z score (this is called standardizing): Thus, P(X < 30) = P(Z < 0.17).
