Psychiatrists believe that learning through physical guidance will improve self-care skills. For 4 months the psychiatrists worked with mentally impaired individuals in which half were taught self-care skills through video imitation and the other half through physical guidance. At the end of the 4 months, individuals were asked to independently perform the self-care task and were rated on the level of required assistance where a higher score indicates more assistance. What can be concluded with an α of 0.05? The rating data are below.
