When I was looking at my chart. I saw that my trial's had a pattern because sometimes I didn't get a high number of squeezes but, then the next trial I get a much higher score. Over all I almost each trial decreased from the earlier trial. The pattern I found in my chart was probably indicating how muscle fatigue works.
My partner's data was kind of similar because they were going up and down, but my partner's (I was in a group of three) got higher score's than me.
I think my results are probably in between being reliable and not reliable. It's toward the non reliable side because my group could've been counting to slow or to fast. It i probably on the reliable side because we had at least two people counting for each other.
