WebbThe Z score is the sum of the left column and the upper row. What is z-score? A z-score is a statistical measure that quantifies how many standard deviations a data point is away from the mean of the dataset. It can be used to describe the distance of a value from the mean in terms of standard deviations. What is a good z-score? WebbBecause the uppercase zeta Ζ is alike to the Latin letter Z, we don't use it much today.

We estimate this as

Webb12 dec. 2004 · To find z such that φ (z)= 0.25, you are looking for a z such that the area under the Normal curve to the left of z is 0.25. By symmetry, this is the same as area to the right of -z. Since your table starts with φ (0)= 0.5 up to φ (infinity)= 1, it is already including the left half. You need to find z such that Φ (z)= 1- 0.25= 0.75.
