Chооse оne scenаrio: Scenаrio 1: The Leаdership Potential Test Standard Deviation (SD): 10; Reliability (r): 0.84; Sarah’s Score (X): 82; Target Reliability: 0.92; Current Items: 50 21. Step 1: Calculate the Standard Error of Measurement (SEM) Formula: SEM = SD * √(1 - r) 22. Step 2: Calculate the 95% Confidence Interval Formula: Interval = Score +/- (1.96 * SEM) 23. Step 3: Determine Required Test Length (Spearman-Brown) Formula: k = [r_new * (1 - r_old)] / [r_old * (1 - r_new)] OR Scenario 2: The Clinical Anxiety Scale Standard Deviation (SD): 12; Reliability (r): 0.75; Participant's Score (X): 60; Target Reliability: 0.90; Current Items: 40 21. Step 1: Calculate the Standard Error of Measurement (SEM) Formula: SEM = SD * √(1 – r) 22. Step 2: Calculate the 95% Confidence Interval Formula: Interval = Score +/- (1.96 * SEM) 23. Step 3: Apply the Spearman-Brown Prophecy Formula Formula: k = [r_new * (1 - r_old)] / [r_old * (1 - r_new)]
