CCO Data Collection & Measurement Techniques 4 — Questions and Answers
Question 1: A correctional facility tracks cell-search results over six months. This is an example of:
- Longitudinal data collection (Correct answer)
- Cross-sectional data collection
- Retrospective case review
- Experimental design
Correct answer: Longitudinal data collection
Longitudinal data collection follows the same variables over an extended period to observe trends and changes.
Question 2: Which measure of central tendency is LEAST affected by extreme outlier values?
- Mean
- Standard deviation
- Median (Correct answer)
- Variance
Correct answer: Median
The median, the middle value in a sorted dataset, is resistant to outliers because it depends on rank rather than magnitude.
Question 3: An officer uses a body-worn camera to capture an altercation. The video footage is an example of:
- Primary quantitative data
- Secondary qualitative data
- Primary qualitative data (Correct answer)
- Secondary quantitative data
Correct answer: Primary qualitative data
Video footage captured directly by the officer is primary data; its descriptive, non-numerical nature makes it qualitative.
Question 4: The range in a dataset of inmate disciplinary violations is calculated by:
- Dividing the total violations by the number of inmates
- Subtracting the smallest value from the largest value (Correct answer)
- Averaging the top and bottom quartile values
- Finding the most frequently occurring value
Correct answer: Subtracting the smallest value from the largest value
The range measures data spread by subtracting the minimum from the maximum value.
Question 5: Which documentation practice violates proper records management in a correctional setting?
- Recording observations in chronological order
- Using approved abbreviations consistently
- Altering a completed report without notation (Correct answer)
- Signing and dating each entry
Correct answer: Altering a completed report without notation
Altering a completed report without a documented correction notation undermines record integrity and may constitute falsification.
Question 6: An officer notes that assaults spike every Friday evening. This pattern is discovered through:
- Experimental research
- Trend analysis of incident data (Correct answer)
- Prospective cohort study
- Nominal data classification
Correct answer: Trend analysis of incident data
Trend analysis examines historical incident data to identify recurring patterns by time, location, or other variables.
Question 7: Which term describes the degree to which a measurement tool actually measures what it claims to measure?
- Reliability
- Precision
- Validity (Correct answer)
- Consistency
Correct answer: Validity
Validity refers to how well an instrument measures the specific concept or variable it is designed to assess.
