The Z-score Calculator is an online tool to measure how many standard deviations an element is from the mean. It efficiently aids in statistical analysis by making complex calculations straightforward and accessible.
Here's the formula for calculating a z-score: z = data point − mean standard deviation. Here's the same formula written with symbols: z = x − μ σ. Here are some important facts about z-scores: A positive z-score says the data point is above average. A negative z-score says the data point is below average. A z-score close to 0.
Raw Score Calculator. Mean: * Standard deviation: * Z-Score: * Answer: 159. Solution: The raw score formula is simply the z-score formula solved for x, the raw score. Depending on what your distribution represents, start by either writing the formula for the raw score of a population: x= μ+zσ x = μ + z σ.
