Biostatistics: A QUICK GUIDE TO THE USE AND CHOICE OF GRAPHS AND CHARTS

Graphs and charts provide a powerful way of summarising data and presenting them in a way that most people find easy to read. They are an important alternative to tables, especially where a dataset is large, but remember that a graphical presentation of data is unlikely to allow your reader to access the raw data if they wish, whilst this is possible with a table. Graphs and charts may alo be useful in assessing data prior to udretaking data analysis or to fitting a numerical model.
