a double-blind experiment was carried out to investigate the effect of the stimulation caffeine on performance on simple physical task. Thirty male college student were trained in finger tapping. they were then decided at random into three groups of ten and the (0,100mg and 200mg) two hours after treatment, each man was required to do finger tapping and the number of taps per minute was recorded. Find the range, average deviation, variance and standard deviation of each dose. Does caffeine affect the performance on this tasks.โ help please
