We statistically studied several problems related to critical flicker fusion frequency (CFF), which was used to design the interlaced scanning method of television systems. Since CFF values closely depend on the physical and mental state of the observer, statistical treatment of data is essential. We studied the difference between up and down discrimination threshold series and the coincidence between CFF values for equal energy colors, mainly by adapting a variance method analysis.
