Random Error or Experimental Error?Please, could you help me by clearing this doubt?
When analyzing the validity of the results using the residual, which of the errors is referred to: experimental error or random error?
Thanks in advance.
Basic Data Analysis and ModelingRe: Random Error or Experimental Error?I'll try my best to answer...but a specific example of your analysis would be helpful. Terminology can be tricky. Experimental error, from an analysis point of view, is the quantity expressed by the mean square for error resulting from the specific model you have fit to a given set of data. Random error is generally the mean square for error as a result of replicate runs in a given set of data. Random error will be a component of experimental error. Most commonly encountered with some manner of lack of fit test. Both can be visualized by examining residual plots in one form or another.
