descriptive statistics

procedures for depicting the main aspects of sample data, without necessarily inferring to a larger population. Descriptive statistics usually include the mean, median, and mode to indicate central tendency, as well as the range and standard deviation that reveal how widely spread the scores are within the sample. Descriptive statistics could also include charts and graphs such as a frequency distribution or histogram, among others. Compare inferential statistics.

sensory evoked potential

a type of evoked potential recorded from electrodes placed on the scalp, overlying the cerebral cortex, in response to sensory stimulation. The stimuli may be visual, auditory, somatosensory, gustatory, or olfactory, and the mapping of sensory evoked potentials in the cortex helps to locate the different sensory areas. See also auditory evoked potential; visual evoked potential. Compare motor evoked potential.
