A data table helps you organize experimental results or research information without a computer. Simply take a pen and paper and name the table, determine the number of rows and columns needed, draw the table, label the columns, put research data in the columns, and finally check your table.
Data tables also help you use your information to make graphs and other charts. Put the title at the top of the page, and make sure it describes all the relevant information. Use a ruler to draw a large box with all the rows and columns, and leave the top row blank so you can label your columns.
Reserve the far left column for your independent variable. For instance, if you're researching the amount of last year's rainfall, your independent variable is the months of the year. Therefore, the far left column is labeled "Month" and the column beside it is labeled "Rainfall."
Make sure all relevant, experimental data is in its appropriate column. When finished, a number should be in every space. For average or derived data results, that number goes in the far right column. Finally, examine your work to ensure all information is correct and clear enough to be readily understood.
