Poweris defined as the probability that a statistical test will reject a false null hypothesis (H0). This can also be stated simply as the likelihood that a study will detect an effect, given that the effect is really there. Power is directly related to Type II error (β), as the following graphical representation of hypothesis … See more Hypothesis testing refers to the fundamental process of evaluating whether data from one group is either consistent with the null hypothesis (H0) or consistent with an … See more The larger a study sample size, the more power the study will have to detect an effect.

WebU. Test Calculator. This is a simple Mann-Whitney U test calculator that provides a detailed breakdown of ranks, calculations, data and so on. The Mann-Whitney U test is a nonparametric test that allows two groups or conditions or treatments to be compared without making the assumption that values are normally distributed. WebYou can select any level of significance you require for the confidence intervals. The odds ratio calculator will output: odds ratio, two-sided confidence interval, left-sided and right-sided confidence interval, one-sided p-value and z-score. If the test was two-sided, you need to multiply the p-value by 2 to get the two-sided p-value.
