Results and Discussion

Note that sometimes in lab reports it may be more appropriate to present the results in one section, called Results, and then to discuss them in a separate Discussion section.

In the Results and Discussion section, you present your results and discuss them by:

  • commenting on the results obtained
  • interpreting what the results mean and
  • explaining any results which are unexpected.

You present the measurements made in the experiment and you then compare your measurements to the calculations you made in your preliminary work or the published theoretical values.

You need to:

  • identify any discrepancies and
  • to state them as a percentage.

You also need to:

  • identify any sources of error in your measurements and
  • if possible, suggest how your experiment could have been performed more accurately.

What should you aim for?

  • Clear comparisons made between the calculations and the measurements with the discrepancy expressed as a percentage.
  • Good explanation of the possible reasons for the discrepancy and the possible sources of error in the measurements.

Example

Here are some useful expressions to use if your measurements correspond well with your calculations:

  • The measurements are consistent with the preliminary calculations.

  • The measured values agree well with the calculated values.

Example

Here are some useful expressions if your measurements do not correspond well with your calculations:

  • The measurements are significantly different from the preliminary calculations.

  • The measured values do not agree well with the calculated values.

Example

Here are some useful expressions for explaining the source of errors:

  • The discrepancy may be due to human error.

  • The difference may be the result of incorrect calibrations.
