Raw score for z score
Webz = (x -μ )/σ. In the above example, x = raw test score value = 170. μ = mean = 135. σ = standard deviation = 20. Input values in the z score formula to calculate the value below. z … WebUsing the z statistic formula above we can easily compute that a raw score from a standard normal distribution is equivalent to the Z score since z = (x - μ) / σ = x for μ = 0 and σ = 1. In another example, a raw score of 1600 from a distribution with mean 1000 and variance 90,000 is given.
