CHARTS OR TABLES?
Charts TablesFewer than 6 data points 7-10 data points More than 10 data points Need to see individual data values Need to show trends over time Need to show the distribution/variation of data
More than 1 independent variable
SOMETIMES YOU MIGHT NEED BOTH
RULES FOR TABLES
anytime / anywhere
TOP TIPS FOR TABLES In presentations,
round the data to “2 effective digits” and use separators
TOP TIPS FOR TABLES Use columns of data
rather than rows; the eye can scan up and down more easily
Put latest data or biggest numbers at the top (unless data is time based)
USING BETTER CHARTS
Avoid common issues
COMMONLY USED CHARTS HAVE A LOT OF ISSUES
