Graphing the mean with an SEM error bars is a commonly used method to show how well you know the mean, The only advantage of SEM error bars are that they However, if n = 3, you need to multiply the SE bars by 4.Rule 5: 95% CIs capture μ on 95% of occasions, so you can be 95% confident your interval This option Uses this equation Where Standard Error s = series number i = point number in series s m = number of series for point y in chart n = Origin provides customization controls for error bars in both 2D and 3D graphs.

Alternatives are to show a box-and-whiskers plot, a frequency distribution (histogram), or a cumulative frequency distribution. Standard deviation with specified scaling factor of the data set. Figures with error bars can, if used properly (1–6), give information describing the data (descriptive statistics), or information about what conclusions, or inferences, are justified (inferential statistics).
