    Linear Mixed Model, a Regression type Statistical Analysis or other?

    I have performed a study on stability where my outcome is continuous and the two inputs are ordinal. Essentially: I am trying to understand if the weight location in a backpack (high, medium, low) and the grade of the road (0%, 5% and 10%) are related to significant differences in stability...

    I already posted on this, but haven't gotten an answer to my core question - which is, what type of statistical analysis should I run. I have many dependent variables I want to measure (change in volume measurements over time) and want to look at how medication effects those changes. I want to...

    is there a Fisher's exact test (or similar) for continuous data?

    I have a simple statistical problem, but am having a hard time identifying a good solution. I am interested in testing to see if an independent factor (length of time interval between 2 different 1 choice tests) influences the association time (a continuous variable) between two options (fast...
