A very large selection (more than 300) of relevant formulas, scores, scales and classifications.

If you have previously purchased MedCalc 3 you can even unlock for free.

In-app purchase lets you unlock the whole range of formulas that MedCalX has to offer more than 300 in total! MedCalX is free to download and use, but you have access only to a subset of formulas. (Version 22.MedCalX is a tool that enables medical professionals to easily use complicated medical formulas, scores and classifications.Ģ0 years of experience developing this tool for mobile platforms makes MedCalX the leading medical calculator, with an unparalleled user interface and powerful features. 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: 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. This procedure calculates the difference between the observed means in two independent samples.
