Homework Help: What data should I put in?

  1. Aug 11, 2009 #1
    I'm doing a practical report on Planck's constant and I have three sets of trials. Is it better to graph all three of them and put them in the report or find the average of the three trials and then graph it and put it in?

    There are no anomalies and all three of the data have very similar results, so which one should I choose?

    I need to know because it will help me in future when writing other practical reports and to be more selective with my data.

    If I'm understanding you correctly, it would be incorrect to average the three trials and then plot the result. Each trial is independent with it's own systematic errors. Your result should be the average of the three end results from the trials.
