Is CI same as p-value?
If the confidence interval does not embrace the value of no difference, then the findings are statistically significant. Thus, confidence intervals provide the same information as a p- value.
How do you know if a CI is statistically significant?
If the confidence interval does not contain the null hypothesis value, the results are statistically significant. If the P value is less than alpha, the confidence interval will not contain the null hypothesis value.
What is the p-value for the t test of equality of means?
0.000
The p-value for the t test for Equality of Means is 0.000, much lower than the p-value significance threshold of 0.05.
What is the meaning of the p value?
The P value is defined as the probability under the assumption of no effect or no difference (null hypothesis), of obtaining a result equal to or more extreme than what was actually observed. The P stands for probability and measures how likely it is that any observed difference between groups is due to chance.
An easy way to remember the relationship between a 95% confidence interval and a p-value of 0.05 is to think of the confidence interval as arms that “embrace” values that are consistent with the data.
Is the p value correct or Iffy?
The conclusion is correct but iffy because the 5% cut-off and even the concept of statistical significance are being challenged. The interpretation is wrong because a Pvalue, even one that is statistically significant, does not determine truth. So, what are the right conclusion and the right interpretation?
What is the pvalue of the chi square test?
The Chi-square test that you apply yields a Pvalue of 0.04, a value that is less than 0.05. You conclude that significantly more patients responded to the antidepressant than to placebo.
