19 Σεπ 2023 · Z-score calculator computes a standardized z-score for any raw data point x. Enter population mean and standard deviation for a given normal distribution.
Z-Score Calculator. You can use this Z-Score Calculator to calculate the standard normal score (z-score) based on the raw score value, the population mean, and the standard deviation of the population. How to use the calculator. Enter the raw score value. Enter the mean, standard deviation, and click the "Calculate" button to see the results.
Calculate the mean as (∑x) / n. Calculate the standard deviation using the easy-to-type formula (∑(x²) - (∑x)²/n) / n. The divisor is modified to n - 1 for sample data. Calculate the z-score using the formula z = (x - mean) / standard deviation.
The Z Score calculates the distance between a data point and the dataset's mean in standard deviations. What is the z-score? The Z score is a statistic that indicates, in terms of standard deviations, how distant a data point is from the dataset's mean.
The z score calculator can be used to derive a z statistic from a raw score and known or estimated distribution mean and standard deviation. If the variance is known instead, then the standard deviation is simply its square root.
Calculator to find out the z-score of a normal distribution, convert between z-score and probability, and find the probability between 2 z-scores.
To use this sample z score calculator, follow the below steps. Choose the data type e.g Data points (s) Input the point separated by commas. Enter the population mean and population standard deviation. Click Calculate Button. Other Calculators. 1. Critical Value Calculator. 2. Coefficient Of Variation Calculator. 3. Mean Calculator. 4.
