angular acceleration experiment

Very quick turn-around on this experiment. Good questions.

However note that you have apparently calculated average angular velocities, and haven't yet calculated accelerations.

I expect a lot of variation in angular accelerations for both experiments. With as much variation as we will likely see here, we probably still won't be able to tell much from only 6 observations of each system.

Calculate the average angular accelerations and see if significant differences emerge.

For some reason my findings do not seem to support what one would think with the magnets upright which should give more wind resistance. Here are my findings." " Ave angular accel r/sec for less air resistance -2.003527601 -2 Ave angular accel r/sec for more air resistance -1.560268949 -1.6 With the magnets uprigth you would expect more air resistance there fore a greater angular accel but in this case there seems to be less angular accel on average in the trials with the magnets upright.
