Since Angelica and Sara's heights vary considerably, the results may be off a little. Since Sara is throwing from a higher position, she may have been able to come closer to Angelica's distances than a shorter novice would have. If the novice thrower worked out regularly, and was strong, then she might have done better than a novice thrower who did not work out. When we were testing the various techniques outside, the toeboard of the ring was loose. Therefore, the distances may be off a little from day to day if the toeboard moved overnight.
Human error has to be considered in the measurements.
When we measured the angles, we paused the tape when the shot had reached its peak. We then drew a line parallel to the ground from where the shot had been initially. From there, we drew a line extending to the shot put. Using a protractor, we then measured the angle of the throw. There was probably errors in the position of the shot, since it is impossible to pause at the exact moment of its peak.
