What Is the Z Score Formula in Statistics? Learn how to calculate a Z score with a simple example! A Z score measures how many standard deviations a data value is above or below the mean. 📌 Z Score Formula: Z = (X − μ) / σ ✅ X = Individual data value ✅ μ = Population mean ✅ σ = Population standard deviation 📚 Simple Example: Score = 85 Mean = 70 Standard Deviation = 10 Z = (85 − 70) / 10 = 1.5 This means the score is 1.5 standard deviations above the mean. 💡 Research Tip: Positive Z Score = Above the mean Negative Z Score = Below the mean Zero Z Score = Equal to the mean 🎓 Explore more research and statistics resources: 🔗 https://www.canyam.com/en
Examples of Z-score Calculations
Simply put, a z-score is the number of standard deviations from the mean a data point is. But more technically it's a measure of how many standard deviations below or above the population mean a raw score is. A z-score is also known as a standard score and it can be placed on a normal distribution curve.
