How To Find The P Value Calculator

Calculating the P Value is a crucial step in statistical hypothesis testing. It helps determine the probability of obtaining results as extreme or more extreme than the observed results under the null hypothesis. Our P Value Calculator simplifies this process, making statistical analysis accessible to everyone.


The P Value is calculated using a complex statistical formula that involves the observed and expected values. The formula takes into account the distribution of the data and provides a probability score. This score helps researchers and analysts make informed decisions about the significance of their findings.

How to Use

  1. Input the observed value into the designated field.
  2. Enter the expected value in the corresponding field.
  3. Click the “Calculate” button to initiate the computation.
  4. The P Value will be displayed in the result field.


Suppose you conducted an experiment with an expected outcome of 50, but the observed result was 55. Input 55 as the observed value and 50 as the expected value. After clicking “Calculate,” the P Value will be revealed, aiding in the interpretation of your experiment’s statistical significance.


  1. What is the P Value? The P Value is a statistical measure that helps assess the evidence against a null hypothesis.
  2. Why is the P Value important? It indicates the probability of obtaining observed results under the assumption that the null hypothesis is true.
  3. How do I interpret the P Value? A smaller P Value suggests stronger evidence against the null hypothesis.
  4. What is considered a “significant” P Value? Typically, a P Value less than 0.05 is considered statistically significant.
  5. Can the P Value be negative? No, the P Value is always between 0 and 1, representing probabilities.
  6. Is a smaller P Value always better? It depends on the context; a smaller P Value may indicate stronger evidence against the null hypothesis.
  7. What if I don’t understand the results? Consult with a statistician or seek guidance from statistical resources.
  8. How does the calculator handle missing values? Both observed and expected values must be provided for accurate calculations.
  9. Can I use this calculator for any statistical test? This calculator is specifically designed for P Value calculations.
  10. What if my observed value is higher than the expected value? The calculator can handle such scenarios, providing insights into the statistical significance of the difference.
