Kirkwood BR, Sterne JAC (2003) Essential medical statistics, 2 nd ed.Altman DG (1991) Practical statistics for medical research.Note that in MedCalc P-values are always two-sided (or two-tailed).

When the P-value is less than 0.05 (P<0.05), the conclusion is that the two means are significantly different. The P-value is the area of the t distribution with n 1 + n 2 − 2 degrees of freedom, that falls outside ± t (see Values of the t distribution table).

The significance level, or P-value, is calculated using the t-test, with the value t calculated as: Welcome to W9B - Most Trusted Web Master Form By The Web Experts Join us now to get access to all our features. The standard error se of the difference between the two means is calculated as: Where s 1 and s 2 are the standard deviations of the two samples with sample sizes n 1 and n 2. The program first calculates the pooled standard deviation s:

Sample size: the number of observations in the sample.

Standard deviation: the observed standard deviation.

The null hypothesis is the hypothesis that the difference is 0. The P-value is the probability of obtaining the observed difference between the samples if the null hypothesis were true. A significance value (P-value) and 95% Confidence Interval (CI) of the difference is reported.
