Statistics for Teaching Science: Part 4 Expressing Error on a Graph
April 9, 2022 @ 10:00 am - 11:30 am EDT$45.00
Error bars are placed on a graph to give a more detailed account of what was observed. Although there are many descriptors that can be used to draw error bars, in each case the value is used to express the uncertainty or variability of the data. Error bars created from certain calculations are especially informative for giving the reader a hint at the significance of the difference seen between two variables, and can at times be a substitute for a statistical hypothesis test. In this workshop, we will practice using error bars on different types of graphs, analyze different data sets, and defend the choices we would make in each case.
This 1.5-hour workshop is open to science and math teachers of all grade levels.
