That\'s it! By following these steps, you can easily calculate the z-score using StatCrunch.

The Mean input in the Normal calculator on StatCrunch represents the average or the central value of the data set. It is the value around which the data tends to cluster. In the context of calculating the z-score, the Mean input is used to calculate the standardized score based on the deviation of a particular data point from the mean. By entering the value of the mean in the Mean input field, the Normal calculator on StatCrunch will use it to determine the relative position of the data point in the distribution and calculate the corresponding z-score.

The Std. Dev. input in the Normal calculator on StatCrunch represents the standard deviation. It is a measure of the spread or dispersion of a set of values. In statistics, the standard deviation is used to quantify the amount of variation or uncertainty in a data set. It tells us how much the values in the data set deviate from the mean.
In the context of the Normal calculator on StatCrunch, the Std. Dev. input is used to calculate the z-score. The z-score is a measure of how many standard deviations a particular value is away from the mean. By entering the standard deviation in the Normal calculator, you are providing the necessary information to calculate the z-score for a given value or range of values.
