WebChi-Square Test N DF Chi-Sq P-Value 225 3 0.648148 0.885. Key Result: P-Value. In these results, the p-value is 0.885. Because the p-value is greater than the chosen α value of 0.05, you fail to reject the null hypothesis. Therefore, you cannot conclude that observed proportions are significantly different from the specified proportions.
WebWhat is the p-value in a chi-square test? The p-value, calculated in a chi-square test, represents an area in the tail of a probability distribution curve. A p-value is a number between zero and one. It is expressed in decimals. For example, a p-value of 0.0254 implies a 2.54% probability that the results could have happened by chance. city and country developersWebFeb 26, 2024 · If the difference between the means is: Near zero (the null hypothesis value), then your p-value will be high.
