Wilcoxon Signed Rank Testmay be used for non-parametric data. AZ-Testis similar to a t-test, but will usually not be used on sample sizes below 30. AChi-Squarecan be used if the data is qualitative rather than quantitative. Comparing More Than Two Groups ...
Therepeated measures ANOVAis used for comparing three or more means when all subjects are measured under a number of different conditions. Repeated measure ANOVA tools in Origin consider three possible designs: One-way Repeated MeasuresPRO ANOVA with one repeated-measures factor. ...
This value is zero when all data points are identical and increases as the data becomes more varied. For instance, when comparing two datasets—one with high variance and another with low variance—you can conclude that the data with high variance is more widely spread than the data with low...
SO similar to Cindy’s question, I am comparing two datasets with 3 number of items (each for positive and negavtive) but they are not always the same. Could I use Kendell’s coefficient to compare these data sets? Could I spread all 40 items in a spreadsheet and rank only the ones ...

When you are comparing an interval/ratio DV across two conditions/time-points (two samples). The research design was repeated measures/within-subjects Characteristics of related samples t test Comparing 2 sets of data obtained from the same subjects who were measured more than once. The main focu...
Any isometry on the Euclidean plane can be uniquely determined by two sets of three non-collinear points; points that determine congruent triangles.Log Transformation of a skewed distribution.Log transformation means taking a data set and taking the natural logarithm of variables. Sometimes your data...

The Mann Whitney U-test is a nonparametric test which is used to compare two treatments in clinical trials and for analyzing the difference between the medians of two data sets. It is an alternative of t-test and the major difference between the two is
