1.4 Summary: Characteristics of Good Data Recording

Here is a summary of good data recording.

1. Raw data is recorded in ink. Data that you think is "bad" is not destroyed. It is noted but kept in case it is needed for future use.

2. The table for raw data is constructed prior to beginning data collection.

3. The table is laid out neatly using a straightedge.

4. The independent variable is recorded in the leftmost column (by convention).

5. The data table is given a descriptive title that makes it clear, which experiment it represents.

6. Each column of the data table is labeled with the name of the variable it contains.

7. Below (or to the side of) each variable name is the name of the unit of measurement (or its symbol) in parentheses.

8. Data is recorded to an appropriate number of decimal places as determined by the precision of the measuring device or the measuring technique.

9. All columns in the table that are the result of a calculation are clearly explained and sample calculations are shown making it clear how each column in the table was determined.

10. The values held constant in the experiment are described and their values are recorded.
