Critical Value Calculator Chi Square. Please enter the necessary parameter values and then click calculate. Since α 0 99 the area under the curve is 1 α 1 0 99 0 01 our critical χ 2 value is 29 1412 in microsoft excel or google sheets you write this function as chiinv 0 01 14 calculate left tailed value.
Critical values are points at the tail s of a certain distribution so that the area under the curve for those points to the tails is equal to the given value of alpha. The chi square test should be run when you want to test how likely it is that an observed distribution is motivated by chance. As such you expected 25 of the 100 students would achieve a grade 5.
