Critical Value Chi Square Distribution Table. This means that we use the column corresponding to 0 95 and row 11 to give a critical value of 19 675. Because of the lack of symmetry of the chi square distribution separate tables are provided for the upper and lower tails of the distribution.
Chi squared distribution table how to use instructions to quickly find the critical value of χ 2 at a stated level of significance α 1 2 3 4 5 10 25 5 etc or α 0 01 0 02 0 03 0 04 0 05 0 1 0 25 0 5 etc for the test of hypothesis in statistics probability surveys or experiments to analyze samples which are not normally or uniformly distributed. To look up an area on the left subtract it from one and then look it up ie. Chi squared distribution table.
Because of the lack of symmetry of the chi square distribution separate tables are provided for the upper and lower tails of the distribution.
This means that we use the column corresponding to 0 95 and row 11 to give a critical value of 19 675. If the chi square statistic that we calculate from our data is greater than or equal to19 675 then we reject the null hypothesis at 5 significance. This means we have sufficient evidence to say the true distribution of customers who come in to this shop on weekends is not equal to 30 on friday 50 on saturday and 20 on sunday. Values of the chi squared distribution.
