We started adding a step-by-step work-through for education purposes, an easy guide on how to calculate test statistics. The calculators also provide R codes for your convenience. We help everybody to calculate statistics. The goal of this website is to make statistics accessible to anyone, converting complex statistical jargon into common everyday language.

The book now includes full coverage of the most commonly used regression models, multiple linear regression, logistic regression, Poisson regression and Cox regression, as well as a chapter on general issues in regression modelling. The second edition of Essential Medical Statistics has been comprehensively revised and updated to include modern statistical methods and modern approaches to statistical analysis, while retaining the approachable and non-mathematical style of the first edition. An introductory textbook, it presents statistics with a clarity and logic that demystifies the subject, while providing a comprehensive coverage of advanced as well as basic methods.

Example: If you are performing one-tailed test for the sample mean of 20, population mean of 15, the size of the population of 5, SD of 25 and the significance level of -10, then you will get the below.

Altman DG (1991) Practical statistics for medical research. This online hypothesis testing calculator for population mean helps you to perform the two-tailed and one-tailed statistical hypothesis testing.

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.
