Charts are the most convenient method of recording these data, since all values are readily available for analysis. Draw a single line through your possible error so it can still be read. Then record new data nearby or in another table if an entire set of measurements is being retaken, because of errors or large discrepancies in circuits, measurements, equipment, etc. As the lab is being performed, results are calculated, etc., be sure to write comments of unusual results, problems encountered, and measures taken to correct the problem or explore unusual results. Note any observations you feel are significant.
Most experiments require a certain number of calculations before final results are obtained.
Formulas and sample calculations that are completely identified must be included. It is not necessary to show repeated calculations. Label axes, plot points accurately and neatly, and circle the points. Discrepancies and unusual results will appear off the line. Graphs should be large.
