An experiment was conducted to compare two methods (namely slide method and digital method) used by medical professionals in obtaining medical images for diagnosis purposes. A group of medical professionals were required to retrieve an image from a library of slides (slide method) and from a computer database (digital method). The time (in seconds) taken for each medical professional to retrieve an image using both methods were recorded. A statistical analysis for the recorded paired data using 3%% significance level was conducted and the Microsoft Excel output is given in Figure 1.
