Which statistical measure BEST represents the spread of student scores on an assessment?
Answer: Standard deviation
Standard deviation quantifies how much scores vary from the mean, directly measuring the spread or dispersion of a score distribution.
A school implements a new reading intervention but only tracks students who complete the full program. This approach introduces which data quality problem?
Answer: Attrition bias
Attrition bias occurs when only completers are analyzed, excluding dropouts who may have lower outcomes, which inflates program effectiveness.
Which of the following is an example of triangulating data to evaluate instructional effectiveness?
Answer: Using test scores, classroom observations, and student work samples together
Triangulation combines multiple data sources to build a more complete and trustworthy picture of instructional effectiveness.
When a standardized test has a ceiling effect, it means:
Answer: Too many high-performing students score at or near the maximum, limiting differentiation
A ceiling effect occurs when the test is too easy for the target group, causing high-performing students to cluster near the maximum score.
A district uses benchmark assessments three times per year. What is the PRIMARY quality assurance purpose of this schedule?
Answer: To monitor student progress and allow mid-year instructional adjustments
Periodic benchmark assessments provide interim data points that allow educators to adjust instruction before the end of the year.
Which action BEST demonstrates a teacher using formative assessment to differentiate instruction?
Answer: Grouping students by quiz results and providing targeted small-group lessons
Using quiz data to form flexible groups and deliver targeted instruction is the hallmark of formative assessment driving differentiation.
A test question asks students to recall a definition but the standard requires students to apply the concept in a new situation. This represents a problem with:
Answer: Construct underrepresentation
Construct underrepresentation occurs when test items fail to capture the full complexity of the skill or standard being assessed.
