A nairalander is in urgent need of the formula for the computation of the chi square statistical analysis to further a project work. Online materials have not been really useful.
Pls post the formula as it should be followed accordingly, plus the chi square table (where we have a collection of two-digit figures). You can also post the formular for gamma Y as it will be needed too.
I'm counting on all Nlanders who can be of help. Please assist a fellow nairalander.
Thanks and GOD bless you!

X^2=(Observed value - Expected value/expected value)^2

Note:
X square denote chi square. If your table is such that have one column and several rows, your degree of freedom would be n-1 that is, number of rows minus 1. But if your table contains more than a row and several columns, then ur degree of freedom would be (r-1)(c-1). You need degree of freedom when checking ur tables.

After your calculation, i.e., your calculated chi square value, compare it to tabulated value. If it is less than the tabulated value, you do not reject null hypothesis, but if it is greather than the calculated value, you reject your null hypothesis.

Your null hypothesis in this case would be the results of ur findings.

For the chi square tables, you can find it in waec/neco four figure tables.

Y u talk so

I appreciate ur effort bro. I also need pictures of all d tables 2 be used nd how 2 use dem

X^2= summation of [( O - E )^2/ E]
while O = observed value
E = expected value
summation sign should be used were u see the summation of, i couldn't find the sign on my phone.
