I am trying to plot and analyze the difference (or similarities) between the path of two spherical pendulums over time. I have Cartesian (X/Y/Z) coordinates from an accelerometer/gyroscope attached to a weight on a string,

If I want to compare the path of two pendulums, such as a spherical pendulum with 5 pounds of weight and another with 15 pounds of weight, how can I analyze this? I am hope to determine how closely the paths match over time.

Thanks in advance.

I am working on a problem where I am trying to find the best way to analyze/present data from a pendulum-type problem. There is a weight on a string and I want to be able to plot how the pendulum moves on the 3D plane and also know how far from center (plumb) the weight is at any given moment in time. I'm struggling with figuring out how to report this so I am hoping someone here can help.

I would also like to know if it is possible to assign an average and standard deviation to the pendulum's swing? How would this be represented on a graph?

I am searching for some resources on A/B/n testing or multivariate/split testing. I am doing an A/B comparison but comparing 3 groups (there may be times when I compare 4); the 3 groups are control, treatment 1, and treatment 2. I found some resources online for A/B testing but as soon as I throw another variable into the mix things get complicated quickly. I cannot seem to find anything that will explain the statistics behind it so I can create a custom calculator. There are a few nice calculators online but they do not fit my needs so I am making something similar in Excel. I have looked at some of the spreadsheets people have made but they are limited to A/B testing and cannot do A/B/n.

Just looking for the theoretical stuff so I can understand and develop from there. Thanks!
