Another good practice is to include a graph or table. A graph is a wonderful visualization of your data, and helps the reader understand what your data look like very well. In most cases, bar graphs with error bars (either standard deviation or 95% confidence interval) or line plots work well. Although you can produce different graphs in R (see more details in [[HCIstats:RGraphics|this page]], I prefer using Excel for producing graphs because it works better with Word. Another practice I do is to include 95% confidence intervals in graphs instead of standard deviations. If you find it hard to make a graph, try to make a table. A table is often a very efficient way to show some values or statistics you have. Try to find out your ways to show your data and stats test results effectively. | Another good practice is to include a graph or table.
