The chi-square test assumes categorical data (attribute data ) and Cochran s Rule requires that mensurate frequencies be at least 5 in each cellphone , although this rule is often relaxed to at most 20 of the anticipate frequencies less than 5 . However , all expected frequencies should be 1 or greater (Doane Seward , 2007The value of t test sta tistics terminate be negative or imperative stock-still , the value of chi square statistic tin cannot be negative and can assume any value from home in to infinity .

For both(prenominal) t distributions and chi-square distribution , there is a incompatible distribution for each possible value of degree of independence . The t-test can be two- tag t test or one tailed (left-tail or right-tail ) test . However , chi-square test is always right-tailed testThere are two types of chi-square test , `Chi-square Goodness-Of-Fit Test and `Chi-square license Test . Chi-square Independence Test is most commonly use d in overt health research (Villeneuve , n ! .dA chi-square test of independence requires an r CH c contingency table that has r rows and c columns .
