    Proper analysis method for dataset involving multiple sessions

    I have a dataset that was collected over 5 discrete sessions, with each session collected on a different date. During each session, 10 human subjects each trained an artificial intelligence program to perform a set of tasks, and additionally, two separate algorithms trained this AI program to...

    Is a Bonferroni correction needed for my particular dataset?

    I received a review of my manuscript in which one of the three reviewers advised that I will need to apply a Bonferroni correction due to multiple comparisons. However, based on the examples I have reviewed, I am not certain that a Bonferroni correction is needed in this case. Here is the...

    Best way to calculate power, precision & sample size using complex pilot data set?

    I have a large and complex pilot data set of electromyographic (EMG) data collected from human subjects performing several different exercises. A single subject was used for all data collection in this pilot experiment. Each data set involves one particular exercise being performed with one...

    p-value associated with Kruskal Wallis with multiple comparison?

    I have a data set that shows the differences between 3 different controllers of a biomechanical system on the same performance metric (specifically, I measure each controller's performance on a set of N tasks, and record the percentage of tasks that achieve success (i.e. the controlled segment...

    Is repeated measures ANOVA appropriate for my data set?

    My project involves designing various controllers of a biomechanical system, and then once the controller design is complete, testing each controller on a single, standard set of 500 tasks, and determining the performance of each controller on this single set of tasks, so that I can compare the...

    Apparent contradiction in Mann-Whitney-Wilcoxon test results

    I have 2 data sets, each N=10, that I would like to compare. They fail Levene's test for homogeneity of variances, and for this reason, I can't use the t-test. I believe that the Mann-Whitney-Wilcoxon nonparametric test is my proper alternative. Here are the data: X1 = [90.4 96.0 94.8 90.4...

    Problem calculating element-wise percent change

    I have 2 data sets that I'm attempting to compare to each other, using a percent change calculation. I have data collected for a physiological model when the muscles aren't fatigued (0fatigue) and the other data set was collected when the muscles were fatigued by 50% (50fatigue). The calculation...
