FAQs on Z Score Calculator and Z Score Calculations
- What is a Z Score? A Z Score measures how many standard deviations a data point is from the mean.
- How do I calculate a Z Score? Subtract the mean from the data point and divide by the standard deviation.
- What does a negative Z Score mean? A negative Z Score indicates a data point below the mean.
- Can I use Z Scores for non-numerical data? Z Scores are typically used for numerical data, but there are alternative methods for categorical data.
