standardized score

a value derived from a raw score by subtracting the mean value of all scores in the set and dividing by the standard deviation of the set. The advantage of standardized scores is that they are not reflective of the units of the measuring device from which they were obtained and thus can be compared to one another regardless of the device’s scale values. Several types of standardized score exist, including stanines, T scores, and z scores. Also called normal score; standard score. See also standardization.

consistent missing

in parapsychology experiments using Zener cards or similar targets, the phenomenon in which a participant’s “calls,” or guesses, are consistently wrong or significantly below chance expectations. Some people attribute such systematic failure to processing error or a conscious or nonconscious reluctance to confirm psychic ability. See also psi-missing.
