What is the degree of freedom of chi-square of 3×3 contingency table?
The number of degrees of freedom in a 3×3 contingency table. Solution: We know that the number of degrees of freedom in a m×n contingency table is (m-1)×(n-1).
How do you calculate chi-square from a table?
In summary, here are the steps you should use in using the chi-square table to find a chi-square value:
- Find the row that corresponds to the relevant degrees of freedom, .
- Find the column headed by the probability of interest…
- Determine the chi-square value where the row and the probability column intersect.

What is the degree of freedom of a 3 * 4 contingency table?
In the case of the 4 × 3 contingency Table 32.4 we obtain a chi-square value of 15.3 with 6 degrees of freedom, which is significant at the 0.05 level of probability as it exceeds the critical value of 12.6.
Is Chi square only for 2×2?
Only chi-square is used instead, because the dependent variable is dichotomous. So, a 2 X 2 (“two-by-two”) chi-square is used when there are two levels of the independent variable and two levels of the dependent variable….

What is the degrees of freedom for a 2×3 chi-square table?

How do you read a contingency table?
The process for calculating conditional probabilities using a contingency table is the following:
- The numerator equals the count of occurrences for the specific combination events in which you’re interested. This count is in a cell.
- The denominator equals the count of occurrences for the “given” portion of the question.
What is contingency table chi-square?
When analysis of categorical data is concerned with more than one variable, two-way tables (also known as contingency tables) are employed. These tables provide a foundation for statistical inference, where statistical tests question the relationship between the variables on the basis of the data observed.
