The Standard Error of Measurement Concept

The standard error of cadence provides a basis for developing the probable limits of an individual's band of lots had the outpouring instrument been administered to the individual multiple times, as contrary to a single administration (Embretson & Hershberger, 1999; Linacre, 1999).

As indicated above, the applicant's assessment leaven realize was 65 and the minimum score for admission into the excess acquaintance program is 70. Addition totallyy, it is known that the standard deviation [SD] of all scores on the entry-assessment canvass is 7.6 and that the reliability [r] coefficient of the entry-assessment test is 0.65. The number one step in applying the standard error of measurement opinion to this case is the calculation of the standard error of measurement [SEM].

The eq

uation for this calculation is as follows:

Based on the 95 percent confidence range of the applicant's true entry-assessment test score, one can state that, at least about of the time, the applicant could be expected to meet or subdue the minimum score of 70 for admission into the special intelligence program. The 95 percent confidence level score range, however, is ground on a normal distribution, which means that most of the applicant's test scores are expected to be in the perfume values of the score range. The probability that the applicant will score 70 or higher on the entry-assessment test, therefore, is much bring low than the probability that the applicant will score 69 or lower on the test. This particular situation, thus, does not appear to be one that justifies the degrading of the established standards for admission to the special scholarship
