Consider measuring the period of a pendulum with a stopwatch. Suppose that the stopwatch is running slow. Which one of the following statements is correct? This will vary our results in both the positive and negative direction, allowing for a varied estimation. We would need to average these errors to obtain our true systematic error. This will lead to overestimation of most of our time results. Systematic errors, unlike random errors, always shift the results in the positive direction. This will lead to underestimation of all of our time results. Systematic errors, unlike random errors, shift the results in one direction. This will not change our estimation because all of our time results will be nearly the same. We would just need to consider random error, not systematic error. QUESTION 2 A student discovers that a photogate consistently reads 5% higher than expected, after all the data is collected. How should this error be handled? The manufacturer's calibration of 1% should be used for the uncertainty in the measurements and the student can ignore the fact that the readings are consistently 5% higher. Knowing the size and direction of the systematic error is not enough to eliminate the effects of this error. Each measurement can be reduced by the same amount (5%) in the first step of the data analysis. Multiple readings should be taken and averaged to reduce the impact of this error. QUESTION 3 The length and width of a living room is 5.5 m and 4.8 m with an uncertainty of 0.1 m in each measurement. The perimeter of the room with associated uncertainty using either the "general method" or the "high/low method": a. 20.6 Â± 0.2 m b. 20.6 Â± 0.1 m c. 20.6 Â± 0.6 m d. 20.6 Â± 0.4 m e. 20.6 Â± 0.8 m
