What does a significant result in the chi square goodness of fit test imply?
If the calculated value of Chi-Square goodness of fit test is greater than the table value, we will reject the null hypothesis and conclude that there is a significant difference between the observed and the expected frequency….Chi-Square Goodness of Fit Test.
| Type of distribution | No of constraints | Degree of freedom |

| Normal distribution | 3 | n-3 |
How do you report significant chi square results?
Chi Square 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: The percentage of participants that were married did not differ by gender, X2(1, N = 90) = 0.89, p > . 05.
What is a large chi square value?
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. There is no significant difference. The amount of difference between expected and actual data is likely just due to chance.
What is the chi square critical value?
3.84
How do you reject the null hypothesis in a chi square test?
If your chi-square calculated value is greater than the chi-square critical value, then you reject your null hypothesis. If your chi-square calculated value is less than the chi-square critical value, then you “fail to reject” your null hypothesis.
What is a good level of significance?
Significance Levels. The significance level for a given hypothesis test is a value for which a P-value less than or equal to is considered statistically significant. Typical values for are 0.1, 0.05, and 0.01. These values correspond to the probability of observing such an extreme value by chance.
What are the different levels of significance?
Popular levels of significance are 10% (0.1), 5% (0.05), 1% (0.01), 0.5% (0.005), and 0.1% (0.001). If a test of significance gives a p-value lower than or equal to the significance level, the null hypothesis is rejected at that level.
