Study Notes
RAT Scores
- The iRAT mean score is 4.9 while the tRAT mean score is 5.9, resulting in an 8% higher overall mean RAT score compared to the individual iRAT score.
Homework Assignments
- Total number of homework and possible extra credit assignments is 0.
Team Bonus Scores
- The mean score from a team bonus with scores of 5, 6, 4, 5, and 15 is 7.
PT Programs Admission Criteria
- PT Program 1 uses norm-referenced measurement, admitting only the top 10% of applicants.
- PT Program 2 employs criterion-referenced measurement, focusing on students with GPA higher than 3.52.
Bloom's Taxonomy
- Achieving the highest level of Bloom's taxonomy involves engaging with problems that have unknown answers.
- Listing levels of Bloom's Taxonomy falls under the 'Remembering' level of thinking.
Student Assessment
- The overall median tRAT letter grade is a B+ based on a median score of 10 and a maximum of 11 points.
Program Comparison
- Determining which PT program has better students is not possible with provided information.
Measurement Types
- Formative assessment is better suited for improving learning outcomes than summative assessment.
- Converting from an ordinal scale to a ratio scale is impossible due to lack of exact score distances in ordinal measurement.
GPA Scoring
- There are 400 possible GPA scores when restricted to two decimal places.
- With unrestricted decimals (0-4), an infinite number of GPA scores is possible.
Data Scales in PT School
- In a specified table,
- Student ID (Column A) is nominal,
- Rank of Applicants (Column B) is ordinal,
- Numeric GRE Score (Column C) is interval,
- Grade in PT school (Column D) is ratio.
Effect of Value Subtraction on Scores
- Subtracting a constant reduces all values and the mean by that constant, but the correlation remains unchanged. Validity is compromised due to shifted values from their true positions.
Validity Assessment
- Validity evaluation requires examination of correlation, slope, and intercept to understand various error aspects.
Depth of Learning
- More than 90% of people need repeated active engagement with material for deep understanding, avoiding superficial retention.
Importance of Primary Sources
- Analyzing primary sources is crucial as information can become less accurate the further it moves from the original source.
Randomized Controlled Trials (RCTs)
- RCTs assess causal relationships through factors like correspondence, precedence, and alternative explanations.
RCT Sample Distribution
- In a parallel design RCT with 20 out of 100 genetically predisposed subjects, if randomized perfectly, 10 will end up in the treatment group.
RCT Results Interpretation
- Conclusions from an RCT on nutritional supplements hinge on factors like sample selection, size, randomization quality, control, and blinding.
Crossover Design Advantage
- Crossover design RCTs effectively address confounders better than parallel group design RCTs.
