The very word strikes fear into the heart of many a biologist (including me). range bars biology In an article published earlier this year, Cumming and co-workers of La Trobe University, Melbourne gave a very useful rundown of common mistakes made when using statistical error bars in biology and suggested a number of rules that should be adhered to when presenting data in this way, especially in publications. This article provides a quick taster of their advice to try and make things seem a little less scary! Two types of error bars are commonly used in biology. Descriptive error bars used to describe a data set and inferential error bars used to determine which conclusions can be justifiably drawn from a data set. These are summarized in the table on the right, which is taken from the paper. Cumming et al suggest 8 rules that should be applied when presenting data: 1. When using error bars always describe what type they are in the figure legend 2. The value of n (the sample size) should always be stated in the figure legend 3. Error bars and statistics should only be shown for independently repeated experiments and never for replicates. If a "representative" experiment shown, it should n

In this article we illustrate some basic features of error bars and explain how they can help communicate data and assist correct interpretation. Error bars may show confidence intervals, standard errors, standard deviations, or other quantities. Different types of error bars give quite different information, and so figure legends must make clear what error bars represent. We suggest eight simple rules to assist with effective use and interpretation of error bars.What are error bars for?Journals that publish science—knowledge gained through repeated observation or experiment—don't just present new conclusions, they also present evidence so readers can verify that the authors' reasoning is correct. Figures with error bars can, if used properly (1–6), give information

Veröffentlicht am 07.05.2014A short movie to show how to produce a graph in Excel for IB Biology, to include error bars for standard deviation. Standard error and 95% confidence limits could also be applied to this simply by substituting the equation for these in place of that for SD.
