            This thesis shows the results of an experiment in order to test the validity of Methods Time 
            Measurement (MTM) data. MTM, developed in 1948, is one of the most commonly used 
            Predetermined Motion Time Systems to calculate standard time for a task. However, there is 
            limited  research  on  the  validity  of  the  MTM  data  in  the  literature.  Today’s  technology 
            provides new computerized tools to perform time studies. One of such tools is Real Time 
            Method Study (RTMS). RTMS is a computerized method study tool being developed in METU 
            Technopolis, which uses Image Processing and Machine Learning to conduct time studies 
            automatically. RTMS uses MTM data as a benchmark data to compare observed performance 
            results;  therefore  validity  of  MTM  data  is  an  important  issue  for  it.  In  order  to  test  the 
            validity of MTM data an experiment conducted in the Ergonomics Laboratory of the METU 
            Industrial Engineering Department. In this experiment 40 undergraduate students performed 
            four different tasks. These tasks were recorded by a video camera and analyzed frame by 
            frame to calculate normal times for basic motions of MTM. Results are compared with the 
            original MTM data and it is shown that MTM times do not fit the observed data. This study in 
            the end suggests updating MTM data or constructing a new standard time database by using 
            a tool like RTMS.
