How To Read P Value From Chi Square Table

how to read p value from chi square table

Chi Square Table T Table

This table matches chi-square values with probabilities, called p-values. Specifically, the table tells you the probability that the differences between your observed and expected values are simply due to random chance or whether some other factor is present. For a goodness-of-fit test, if the p-value is 0.05 or less, then you must reject your prediction.

Table Chi-Square Probabilities

The key result in the Chi-Square Tests table is the Pearson Chi-Square. The value of the test statistic is 3.171. The footnote for this statistic pertains to the expected cell count assumption (i.e., expected cell counts are all greater than 5): no cells had an expected count less than 5, so this assumption was met.

Look up the Chi-square value in a table to see if it is big enough to indicate a significant difference in handedness of males and females. Interpretation . Greater differences between expected and actual data produce a larger Chi-square value. The larger the Chi-square value, the greater the probability that there really is a significant difference. With a 2 by 2 table like this (If you have

Analysing Tables Part V Interpreting Chi-Square 8.0

For a chi-square test of the independence of two categorical variables, we have a two-way contingency table with r rows and c columns. The number of degrees of freedom is ( r - 1)( c - 1). In this table, the number of degrees of freedom corresponds to the row that we will use.

Now, at least theoretically, you could also use the chi-square table to find the probability associated with a particular chi-square value. But, as you can see, the table is pretty limited in that direction. For example, if you have a chi-square random variable with 5 degrees of freedom, you could only find the probabilities associated with the chi-square values of 0.554, 0.831, 1.145, 1.610
