Question

You create a plot of 1/dI (in 1/m) vs. 1/dO (in 1/m) from the data you took for an unknown lens. If the slope of the best-fit line is −1.233 ± 0.04028, should you be concerned about the quality of your data? (note that the slope should be -1)

Answer 1

The deviation in the slope of the best-fit line is within the range of uncertainty, so the quality of the data is not a concern.

Step-by-step explanation:

The slope of the best-fit line calculated from the data collected for the unknown lens is -1.233 ± 0.04028. Since the expected slope is -1, the deviation from the expected value is 0.233. A deviation of this magnitude is within the range of the uncertainty, which is 0.04028. Therefore, it is not necessary to be concerned about the quality of the data.
