Answer to Question 1

ANS: B
Reliability exists in degrees and is usually expressed as a form of correlation coefficient, with 1.00 indicating perfect reliability and .00 indicating no reliability.
Equivalence of items is determined with parallel forms reliability.
Test-retest reliability determines stability of an instrument.
Correlation coefficients do not determine validity.

Answer to Question 2

ANS: B
Reliability is concerned with the consistency of the measurement technique. Precision is the degree of consistency or reproducibility of measurements using physiological instruments. Thus precision is comparable with reliability.
Accuracy is connected with the validity of the instrument.
Selectivity has to do with whether an instrument can measure what the researcher wants while only measuring what the researcher wants.
Sensitivity refers to the ability of an instrument to detect minute changes between measures and/or subjects.
