    What is the Chi Square Distribution?

    Chi Square distribution; It is used to investigate the difference between the expected value and the observed value (Is the difference between them meaningful?). It shows how much a system fits to a certain probability distribution by the square of differences method. You will compare the sum of the squares of the differences and the corresponding chi square value, while there are values observed and values you expect to be observed.
