Chi-Squared ( χ2 ) Statistics  

The 

χstatistic is a measure of the goodness of fit between data and an 

assumed distribution.

*  It  is  used  to  test  whether  a  set  of  observed 

frequencies differs from a set of expected frequencies sufficiently to 
reject the hypothesis under which the expected frequencies were 
obtained. 
 

 

* The statistic can be assumed to be χ2 distributed with n–1 degrees of freedom 

if n or some of the E

i values are large.
