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.

Since the z-score is the number of standard deviations above the mean, z = (x - mu)/sigma. Solving for the data value, x, gives the formula x = z*sigma + mu. So ...

The Z-score is calculated by finding the difference between a data point and the average of the dataset, then dividing that difference by the standard deviation ...

19 сент. 2023 г. · Z-score calculator computes a standardized z-score for any raw data point x. Enter population mean and standard deviation for a given normal ...

21 июл. 2024 г. · If you know the mean and standard deviation, you can find the z-score using the formula z = (x - μ) / σ where x is your data point, μ is the ...

28 июн. 2024 г. · How to calculate a Z-score · 1. Determine the mean · 2. Choose a value for x · 3. Find the standard deviation · 4. Perform the calculation.

Overview ... z = (x-μ) / σ,. where μ is the population mean and σ is the population standard deviation. Note: if you don't know the population standard deviation ...

This simple calculator allows you to calculate a standardized z-score for any raw value of X. Just enter your raw score, population mean and standard deviation, ...

The formula for the Z-score is z = x − μ σ , where x is the data point of interest, μ is the population mean, and σ is the population standard deviation.
