Data Interpretation
4. The standard error (SE), which indicates how greatly the mean
would likely vary if the experiment was repeated, is calculated as
SE =
Vn
As a rough rule of thumb, if an experiment is to be repeated, the
new mean would typically lie within two standard errors of the
original mean (that is, within the range X± 2SE). Calculate X+
2SE for each treatment, determine whether these ranges overlap,
and interpret your results.
