A paired difference test, better known as a paired comparison, is a type of location test that is used when comparing two sets of paired measurements to assess whether their population means differ. A paired difference test is designed for situations where there is dependence between pairs of measurements (in which case a test designed for ...
Since the null hypothesis for Tukey's test states that all means being compared are from the same population (i.e. μ 1 = μ 2 = μ 3 = ... = μ k), the means should be normally distributed (according to the central limit theorem) with the same model standard deviation σ, estimated by the merged standard error, , for all the samples; its ...

To determine if there is a significant difference between two means with equal sample sizes, the Newman–Keuls method uses a formula that is identical to the one used in Tukey's range test, which calculates the q value by taking the difference between two sample means and dividing it by the standard error:
In a confirmatory or primary screen with replicates, for the i-th test compound with replicates, we calculate the paired difference between the measured value (usually on the log scale) of the compound and the median value of a negative control in a plate, then obtain the mean ¯ and variance of the paired difference across replicates.
People with severe apathy tend to have a lower quality of life and are at a higher risk for mortality and early institutionalization. [2] They may also exhibit insensibility or sluggishness . [ 4 ] In positive psychology , apathy is described as a result of the individuals' feeling they do not possess the level of skill required to confront a ...
