Table Chi Squared Distribution. To look up an area on the left subtract it from one and then look it up ie. The areas given across the top are the areas to the right of the critical value.
How to use chi squared table. Chi square distribution table d f. We ll call this distribution x 2 k thus if z1 zk are all standard normal random variables i e each zi n 0 1 and if they are independent then.
In probability theory and statistics the chi square distribution with k degrees of freedom is the distribution of a sum of the squares of k independent standard normal random variables.
The alpha level for the test common choices are 0 01 0 05 and 0 10 the following image shows the first 20 rows of the chi square distribution table with the degrees of freedom along the left side of the table and the alpha levels along the top of the table. The first row represents the probability values and the first column represent the degrees of freedom. The chi square distribution table is a table that shows the critical values of the chi square distribution. How to use chi squared table.
