True or False: Random errors are always consistent.
Think about fluctuations in repeated measurements.
You measure a substance three times with results of 2.00 g, 2.01 g, and 1.99 g. Calculate the average and the standard deviation of these measurements.
Use the standard deviation formula considering how far each measurement varies from the mean.
If your experimental result is 15.2 ± 0.2 (in mm), compare this with a theoretical value of 15.5 mm. Are these results significantly different?
Consider how uncertainty influences significance in measurements.
