WebMar 24, 2024 · Calculating Z Scores 1 Use the following format to find a z-score: z = X - μ / σ. This formula allows you to calculate a z-score for any data point in your sample. [19] Remember, a z-score is a measure of how many standard deviations a data point is away from the mean. In the formula X represents the figure you want to examine.

WebFinding a Z Score in R. Suppose you have been given a p value; this would be the percentage of observations that lie towards the left of the value that it corresponds to within the cumulative distribution function. If, for example, your p value is 0.80, it would be the point below which 80% of the observations lie, and above it, 20%. WebMar 30, 2024 · To find a Z critical value for a given confidence level α: Check if you perform a one- or two-tailed test. For a one-tailed test: Left-tailed: critical value is the α-th quantile of the standard normal distribution N(0,1). Right-tailed: critical value is the (1-α)-th quantile.
