Because you can have access to two pieces of information but may not be able to manipulate the variables. Lots of different tests selected on the basis of the characteristics of the study (compares mean scores) Is the process through which the senses detect visual, auditory, and other sensory stimuli and transmit them to the brain. Is the process by which sensory information is actively organized and interpreted by the brain. The difference between not being able to perceive a stimulus and being able to just barely perceive it. The minimum amount of sensory stimulation that can be detected 50% of the time. The smallest increase in a stimulus that is required to notice a difference. Difference that is detectable 50% of the time. Become less sensitive to an unchanging sensory stimulus over time.
