SUMMARY

The discussion focuses on the appropriate representation of significant figures when the uncertainty exceeds the measured values. The average calculated is -0.7101, with a standard deviation of 1.7506. Participants emphasize that reporting the average as -0.7 ± 1.8 or -1 ± 2 is misleading due to the standard deviation being larger than the average. The consensus is to express results in a way that accurately reflects the uncertainty, potentially using a broader range of values to convey the lack of precision.

PREREQUISITES
  • Understanding of significant figures in scientific reporting
  • Basic knowledge of statistical concepts such as mean and standard deviation

NEXT STEPS
  • Research best practices for reporting significant figures in scientific results
  • Learn about the implications of standard deviation in data interpretation
  • Explore methods for communicating uncertainty in experimental data
  • Investigate statistical software tools for data analysis and reporting
USEFUL FOR

Researchers, laboratory technicians, and students in scientific fields who need to accurately report experimental data and understand the implications of uncertainty in measurements.

Hey, so in my lab I took some apparently bad data and when I averaged it and took the standard deviation I got values for the SD that were larger than the average of the data. I'm sure they still want sig figs in the results but I'm not sure how to report it.

My average is -0.7101 and my standard deviation is 1.7506..

What is wrong with -0.7 +/- 1.8 or -1 +/- 2?

The book claims the answer is that all the magnitudes are the same because "the gravitational force on the penguin is the same". I'm having trouble understanding this. I thought the buoyant force was equal to the weight of the fluid displaced. Weight depends on mass which depends on density. Therefore, due to the differing densities the buoyant force will be different in each case? Is this incorrect?
