This tool calculates the cumulative distribution function (CDF) values for your specified probability distribution.
How to Use the Calculator:
To calculate the cumulative distribution function (CDF) from the probability density function (PDF) for a normal distribution, you need to input the mean (μ), standard deviation (σ), lower bound (X1), and upper bound (X2).
- Mean (μ): The average value of the dataset.
- Standard Deviation (σ): A measure of the amount of variation or dispersion of a dataset.
- Lower Bound (X1): The lower threshold for which you want to calculate the CDF.
- Upper Bound (X2): The upper threshold for which you want to calculate the CDF.
Click the ‘Calculate’ button to see the results. The calculator uses the cumulative distribution function of a standard normal distribution (mean 0, standard deviation 1). If X1 or X2 is not within the practical range (±6σ), the calculation might be less accurate.
