- Title the table; make sure the title relates to the data you will put in your table. The data table title is NOT a repeat of the research question; the title SHOULD be descriptive of the data contained in the table.
- Figure out how many columns and rows are needed. Rows are a series of horizontal cells and columns are a series of vertical cells. Although not required, in most cases the manipulated variable (that which is purposefully changed) is in the left column, the raw data for the responding variable (that which you measure) with the different trials is in the next columns, and the processed data (often average and standard deviation) is in the far right column. Be sure to include a row for the heading of each column.
- Draw the table either by hand or within a software program like Microsoft Excel or Google Sheets. Show lines around all rows and columns. Be sure the table does not break across multiple pages.
- Label the columns, including units and measurement uncertainty of the raw data.
- Record the data from the experiment or research in the appropriate columns. The information in the table must be clear and obvious to anyone who sees it. When you're finished there should be a number in every space. All numerical values must have the consistent and correct number of digits. There should be no variation in the precision of the data; the same number of decimal places (significant digits) should be used.
- Check your table. Look over the work to make sure everything is correct and clear.
