Here are the matches for the question.
1. Declares that the mean of a distribution of scores is 100 and
the standard deviation is 15. - T score
2. Scores with a mean of 10 and a standard deviation of 3;
frequently used to report subtest or subscale scores. -
Interpretative range
3. A system that divides the normal curve into nine equidistant
segments. - Stanine
4. Method for dividing a percentile rank distribution into four
portions. - Quartile
5. Scores used on most intelligence, achievement, and perceptual
skills tests. - Deviation IQ
6. Has a mean of zero, a standard deviation of one, and is computed
from the raw score distribution. - Scaled
score

of 21.06. - Standard score
8. A bell-shaped, mathematically defined, smooth curve in which the
mean, median, and mode lie at the exact center. - Normal
curve
9. Can help convey performance information to individuals who may
be unsophisticated in test score interpretation. -

11. Indicate the percentage of observations that fall below a given
score on a measure plus one-half of the observations falling at the
given score. - Z-score
