What is the difference between odds ratio and Chi square?

none

If the coefficient of determination is 0.81 the coefficient of correlation?

Given co-efficient of determination, r2 = 0.81. co-efficient of correlation, r = square root of 0.81 = +0.9, if the data have move in the same direction.(Let x and y as variables then x and y have linear relationship and x increase or decrease and y also have increase or decrease) = -0.9, if the data have move in the opposite direction.(Let x and y as variables then x and y have linear relationship and x decrease or increase and y is also increase or decrease)

What does the coefficient of determination explain in regression?

The coefficient, also commonly known as R-square, is used as a guideline to measure the accuracy of the model.

How does the difference between fe and fo influence the outcome of a chi-square test?

The larger the difference, the larger the value of chi-square and the greater the likelihood of rejecting the null hypothesis
