1. Why do we need to use a weighted average for the measurements made with the caliper? How
much does your weighted average differ from a non-weighted average?
2. When can you replace a weighted average with a non-weighted average and why?
3. The statistical analysis method assumes that all of your measurements are independent of each
other and randomly distributed about the best estimate for the mean. Is this a valid assumption?
