Abstract:
This retrospective, comparative study examined the effect of increasing objectivity of evaluation methods on grade inflation in a graduate nursing research course. Multiple-choice testing and increased precision in grading rubrics were added to the course. Outcome measures of student grade distributions for the course were measured pre/post course revision. Statistically significant reductions in grade distributions were observed after course evaluation method revisions were implemented (U = 4575.0, P < .001).

Testing a Claim about Standard Deviation
The hypothesis testing for the claim of population standard deviation (or variance) requires the data and samples to be random and unbiased. The population distribution also must be normal. There is no specific requirement on the sample size as the estimation is based on the chi-square distribution.
As a first step, the hypothesis (null and alternative) concerning the claim about...
Ratio Level of Measurement
A set of data measured using the ratio scale takes care of the ratio problem and provides complete information. Ratio scale data are like interval scale data, except they have a zero point and ratios can be calculated....

Types of Aggregate Grading
Well-graded aggregates include a complete range of necessary size fractions that fit together to create a dense matrix with minimal voids, represented by a smooth, continuous gradation curve. This type of grading ensures good...
