MDE Data Literacy and Interpretation 1 — Questions and Answers
Question 1: In educational assessment, which term describes data expressed in numerical form that can be statistically analyzed?
- Qualitative data
- Quantitative data (Correct answer)
- Observational data
- Narrative data
Correct answer: Quantitative data
Quantitative data is expressed numerically and is suitable for statistical analysis, such as test scores and attendance rates.
Question 2: What does a percentile rank of 75 indicate for a student's test score?
- The student answered 75% of questions correctly
- The student scored higher than 75% of the norm group (Correct answer)
- The student is at the 75th grade equivalent level
- The student needs 75% more improvement to reach proficiency
Correct answer: The student scored higher than 75% of the norm group
A percentile rank of 75 means the student scored higher than 75% of the students in the comparison group, not that they got 75% correct.
Question 3: In Minnesota, which statewide assessment provides annual data on student achievement in reading and mathematics?
- NAEP (National Assessment of Educational Progress)
- MCA (Minnesota Comprehensive Assessments) (Correct answer)
- ACT (American College Testing)
- MAP (Measures of Academic Progress)
Correct answer: MCA (Minnesota Comprehensive Assessments)
The Minnesota Comprehensive Assessments (MCA) are the state's primary annual assessments that measure student proficiency in reading and mathematics.
Question 4: What is the primary purpose of disaggregating student achievement data by subgroup in Minnesota?
- To rank schools against each other statewide
- To identify and address achievement gaps among different student populations (Correct answer)
- To determine teacher salary increases
- To compare Minnesota students to national averages
Correct answer: To identify and address achievement gaps among different student populations
Disaggregating data by subgroup (e.g., race, income, disability status) reveals performance disparities so educators can target supports to close achievement gaps.
Question 5: Which measure of central tendency is most affected by extreme outlier scores in a data set?
- Median
- Mode
- Mean (Correct answer)
- Percentile
Correct answer: Mean
The mean (average) is most sensitive to outliers because all values are summed together, so extreme scores can significantly skew the result.
Question 6: What does 'reliability' mean in the context of educational assessments?
- The assessment measures what it claims to measure
- The assessment consistently produces similar results under similar conditions (Correct answer)
- The assessment is free from cultural bias
- The assessment covers all required content standards
Correct answer: The assessment consistently produces similar results under similar conditions
Reliability refers to the consistency of assessment results — a reliable assessment produces similar scores when administered to the same students under comparable conditions.
Question 7: When a school's score distribution shows a bimodal pattern, what does this typically indicate?
- Most students scored near the class average
- There are two distinct groups of students performing at different levels (Correct answer)
- The test was too easy for most students
- Data collection errors occurred during testing
Correct answer: There are two distinct groups of students performing at different levels
A bimodal distribution shows two peaks, indicating two distinct subgroups within the student population who are performing at significantly different levels.
