It is commonly used in statistical analysis to compare and standardize data across different distributions. The z-score represents the number of standard deviations away from the mean the data point is located.īy following these steps, you can easily calculate the z-score using StatCrunch.Ī z-score, also known as a standard score, is a statistical measurement that explains how many standard deviations an observation or data point is from the mean of a dataset. The z-score along with the associated p-value will be displayed. Click on the \"Calculate\" button to generate the z-score.Ĩ. Choose the appropriate comparison operator (, ≤, or ≥) depending on the specific question or problem at hand.ħ. Fill in the input field with the desired value of X, which is the data point in question.Ħ. This value represents a specific data point within the distribution.ĥ. Determine the value for which you want to find the z-score. These values are usually provided in the question or can be derived from the given data.Ĥ. Enter the mean and standard deviation of the distribution in the designated fields. Select the \"Normal\" calculator from the options listed.ģ. Open StatCrunch and navigate to the \"Calculators\" section.Ģ. To calculate a z-score on StatCrunch, follow these steps:ġ.
