Is My Data Significant?

About this project

How to use: Enter your expected data on the left side, and your actual data on the right side. For example, if you were flipping what you think is a fair coin, the two numbers on the left should be the same, and the numbers on the right would be the numbers of heads and tails.

About this project: This uses a chi-squared test and SciPy to calculate the probability that the data on the right is significantly different from the data on the left. It uses (number of rows - 1) degrees of freedom.

Source files:

• stats.cgi - the Python script that does the cgi-squared calculation using SciPy.
• stats.js - the JavaScript file that manages the adding/removing of rows, sends the data to stats.cgi and prints the results.
