About Inverse Z Score Calculator (Formula)
An Inverse Z Score Calculator is a tool used in statistics to find the raw score or data value associated with a specific z-score in a standard normal distribution. Z-scores are used to measure how far a particular data point is from the mean (average) in terms of standard deviations. The formula for calculating the inverse z-score, also known as finding the raw score from a z-score, is as follows:
Raw Score = (Z-Score * Standard Deviation) + Mean
Where:
- Raw Score is the data value you want to find.
- Z-Score is the z-score from the standard normal distribution.
- Standard Deviation is the standard deviation of the dataset.
- Mean is the mean (average) of the dataset.
This calculator is particularly useful when you have a z-score and want to know the corresponding data value in the original dataset. It’s commonly used in fields such as statistics, finance, and quality control to interpret and work with standardized data. The Inverse Z Score Calculator simplifies this calculation process, providing quick and accurate results.
