Tables

Tables organize data and information into groups by means of numbers and/or text. They are best at presenting data. A table is always referred to as a table. All other items are referred to as figures.

  • Which items are these?

 

Figures

Figures are visual arrangements of data and results. Figures are best at showing the relationships between data, its trends and patterns.

When do we use tables and figures? Which one should we use?

That depends on the kind and amount of information. Sometimes tables or figures are unnecessary because results are best presented parenthetically in a single sentence, for example:

Seed production was higher for plants in the full-sun treatment (52.3 +/-6.8 seeds) than for those receiving filtered light (14.7+/- 3.2 seeds).
  • So, when do we use them?

A good answer would be that you should use them when the situation naturally requires them, i.e. when a complicated piece of information would be best understood by the reader in a table or figure rather than in a chunk of written text.

  • Which one should we use, a table or a figure?

It depends on the information and the effect you want to convey. Basically the same data can be presented in a table or in a figure. Usually, figures are more powerful and appealing, but less precise than a table.

In some cases it is difficult to decide which one works best. Readers expect certain data to be presented in a certain way, and it is important to benefit from this expectation when choosing the way of making your data available. Click on the following exercise to find out the purposes that different kinds of tables and figures serve best:

 

Using tables and figures properly is as important for your research article as writing a satisfactory introduction. So, before actually writing tables and figures, it is a good idea to do the following:

  • decide which data and results will go in a table or figure, and which will not.
  • decide on the order. Your tables and figures must 'tell a story', i.e. escort the reader logically through the steps of the discussion.
