WebEnter the Chi-Square table at df = 3 and we see the probability of our chi-square value is greater than 0.90. By statistical convention, we use the 0.05 probability level as our critical value. If the calculated chi-square value is less than the 0 .05 value, we accept the hypothesis. If the value is greater than the value, we reject the hypothesis. WebDetermine degrees of freedom and locate the value in the appropriate column. Locate the value closest to your calculated 2 on that degrees of freedom df row.

WebBy doing the calculations (shown later), we come up with: P value is 0.043 In this case p < 0.05, so this result is thought of as being "significant" meaning we think the variables are not independent. In other words, because 0.043 < 0.05 we think that Gender is linked to Pet Preference (Men and Women have different preferences for Cats and Dogs).
