How do you interpret Pearson chi square value?
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 does the chi-square test statistic tell you?
The chi-squared statistic is a single number that tells you how much difference exists between your observed counts and the counts you would expect if there were no relationship at all in the population.
What does a low Pearson chi square value mean?
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.
What is a high 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.
How do you interpret Pearson chi-square results in SPSS?
Put simply, the more these values diverge from each other, the higher the chi square score, the more likely it is to be significant, and the more likely it is we’ll reject the null hypothesis and conclude the variables are associated with each other.

Interpret the key results for Descriptive Statistics
- Step 1: Describe the size of your sample.
- Step 2: Describe the center of your data.
- Step 3: Describe the spread of your data.
- Step 4: Assess the shape and spread of your data distribution.
- Compare data from different groups.
How do you report chi-square results in a table?
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.
How do you interpret Pearson chi square results in SPSS?
Do you want a high or low chi squared?
The larger the Chi-square value, the greater the probability that there really is a significant difference. There is a significant difference between the groups we are studying.
How do you Analyse a chi-square test?
Interpret the key results for Chi-Square Test for Association
- Step 1: Determine whether the association between the variables is statistically significant.
- Step 2: Examine the differences between expected counts and observed counts to determine which variable levels may have the most impact on association.
How do you analyze chi-square data?
Let us look at the step-by-step approach to calculate the chi-square value:
- Step 1: Subtract each expected frequency from the related observed frequency.
- Step 2: Square each value obtained in step 1, i.e. (O-E)2.
- Step 3: Divide all the values obtained in step 2 by the related expected frequencies i.e. (O-E)2/E.
How do you analyze a chi-square test?
Is .02 statistically significant?
If the p-value comes in at 0.2 the result is not statistically significant, but since the boost is so large you’ll likely still proceed, though perhaps with a bit more caution.
How do you determine if data is statistically significant?
To carry out a Z-test, find a Z-score for your test or study and convert it to a P-value. If your P-value is lower than the significance level, you can conclude that your observation is statistically significant.
How do you analyze a Chi-square test?
How do you read a chi-square table?
The critical values within the table are often compared to the test statistic of a Chi-Square test. If the test statistic is greater than the critical value found in the table, then you can reject the null hypothesis of the Chi-Square test and conclude that the results of the test are statistically significant.
