For confidence intervals a critical value is one of the ingredients that goes into the calculation of a margin of error. For upper tail one sided tests the test statistic is compared with a value from the table of upper tail critical values. While you may be thinking that the test is already complete and that you can withdraw a conclusion from ere the reality is that you re still a halfway.
The use of a chi square table that we will examine is to determine a critical value.
To look up an area on the left subtract it from one and then look it up ie. Because of the lack of symmetry of the chi square distribution separate tables are provided for the upper and lower tails of the distribution. For confidence intervals a critical value is one of the ingredients that goes into the calculation of a margin of error. The use of a chi square table that we will examine is to determine a critical value.
