WebJan 31, 2024 · Z = (x - mean)/standard deviation. Assuming that the underlying distribution is normal, we can construct a formula to calculate z-score from given percentile T%. Note that InvNorm (T) is a TI function, similarly we can use excel function Norm.Inv (T, 0, 1) For example, z-score of 30th percentile is InvNorm (0.3) = -0.52. WebMar 6, 2024 · The NORM.INV function is designed to work with the left portion of our distribution. When we ask about an upper proportion we are looking at the right-hand side. The top 1% is equivalent to asking about the bottom 99%. We enter =NORM.INV (.99,100,15). The output from Excel is approximately 134.90. You can use the invNorm() function on a TI-84 calculator to find z critical values associated with the normal distribution.
