ERROR BARS
Description:
An error bar is a line through a point on a graph, parallel to one of the axes, which represents the uncertainty of the corresponding coordinate of the point.
Error Bars help to indicate estimated error or uncertainty to give a general sense of how exact a measurement is.
- Error Bars can be applied to graphs such as Scatter Plots, Dot Plots, Bar Charts or Line Graphs.
- This is done through the use of markers drawn over the original graph and its data points.
- Typically, Error bars are used to display either the standard deviation, standard error, confidence intervals or the minimum and maximum values in a ranged data-set.
- 1st and 2nd column represents X and Y data-set, 3rd column represents error.
