In chi-square statistics - how are you able to determine multiple degrees of freedoms?

Solutions

Expert Solution

To determine multiple degrees of freedoms for chi square statistics with different levels of significance, We can use standard chi square table which is attached herewith.

With row, degrees of freedom varies and level of significance varies with column.

Thannk you.
