Chi-Square Distribution


This chapter discusses about the chi-square distribution. Basically chi-square distribution is the measure of which enables us to find out the degree of degree of discrepancy between the observed and expected frequencies. In this chapter we discuss the uses of chi-square test as a test for goodness of fit, as a test for independence of attributes and homogeneity chi-square.
