The Chi Square Test - University of West Georgia
www.westga.eduThe chi-square test for a two-way table with r rows and c columns uses critical values from the chi-square distribution with ( r – 1)(c – 1) degrees of freedom. The P-value is the area under the density curve of this chi -square distribution to the right of the value
Mendelian Inheritance & Probability
www.csus.eduThe Chi Square Test • A statistical method used to determine goodness of fit – Goodness of fit refers to how close the observed data are to those predicted from a hypothesis • Note: – The chi square test does not prove that a hypothesis is correct • It evaluates whether or not the data and the hypothesis have a good fit
t-Tests, Chi-squares, Phi, Correlations: It’s all the same ...
web.pdx.eduChi-square tests are based on the normal distribution (remember that z2 = χ2), but the significance test for correlation uses the t-distribution. With large sample sizes (e.g., N > 120) the t and the normal z-distributions will be the same (or, at least, extremely close).1.
