AdministratorHow do you interpret the p value in a chi square test?
For a Chi-square test, a p-value that is less than or equal to your significance level indicates there is sufficient evidence to conclude that the observed distribution is not the same as the expected distribution. You can conclude that a relationship exists between the categorical variables.
How do you report statistics in APA?
Reporting Statistics in APA Style
- Percentages are also most clearly displayed in parentheses with no decimal places:
- Chi-Square statistics are reported with degrees of freedom and sample size in parentheses, the Pearson chi-square value (rounded to two decimal places), and the significance level:

What does a high chi-square value mean?
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. The amount of difference between expected and actual data is likely just due to chance.
What is a significant chi-square value?
The likelihood chi-square statistic is 11.816 and the p-value = 0.019. Therefore, at a significance level of 0.05, you can conclude that the association between the variables is statistically significant.
What is Chi Square in research?
A chi-square test is a statistical test used to compare observed results with expected results. The purpose of this test is to determine if a difference between observed data and expected data is due to chance, or if it is due to a relationship between the variables you are studying.
Is it good to reject the null hypothesis?
Null hypothesis are never accepted. We either reject them or fail to reject them. The distinction between “acceptance” and “failure to reject” is best understood in terms of confidence intervals. Failing to reject a hypothesis means a confidence interval contains a value of “no difference”.
How do you determine if chi-square results are statistically significant?
You could take your calculated chi-square value and compare it to a critical value from a chi-square table. If the chi-square value is more than the critical value, then there is a significant difference. You could also use a p-value. First state the null hypothesis and the alternate hypothesis.
At what P value is the null hypothesis rejected?
0.05
What does P value of 0.001 mean?
p=0.001 means that the chances are only 1 in a thousand. The choice of significance level at which you reject null hypothesis is arbitrary. Conventionally, 5%, 1% and 0.1% levels are used. Conventionally, p < 0.05 is referred as statistically significant and p < 0.001 as statistically highly significant.
