Guitar Research & Evidence-Based Practice 4 — Questions and Answers
Question 1: Which type of validity concerns whether a guitar technique assessment actually measures technique skill rather than reading ability or test anxiety?
- External validity
- Construct validity (Correct answer)
- Temporal validity
- Face validity
Correct answer: Construct validity
Construct validity evaluates whether a test truly measures the theoretical construct it claims to measure, such as guitar technique rather than a confounded skill.
Question 2: A meta-analysis on guitar practice finds a 'funnel plot asymmetry.' What does this most likely indicate?
- The studies used different guitar tunings
- Possible publication bias favoring positive results (Correct answer)
- High heterogeneity in participant age
- An error in the statistical software
Correct answer: Possible publication bias favoring positive results
Funnel plot asymmetry in a meta-analysis typically signals publication bias, where studies with positive or significant results are more likely to be published.
Question 3: Which research design would be MOST appropriate for studying the lived experience of recovering from a guitar-related hand injury?
- Double-blind randomized trial
- Phenomenological qualitative study (Correct answer)
- Time-series analysis
- Correlational survey
Correct answer: Phenomenological qualitative study
Phenomenology explores participants' lived experiences and subjective meaning-making, making it ideal for studying personal recovery journeys.
Question 4: In evidence-based guitar instruction, a 'systematic review' differs from a traditional narrative review primarily because it:
- Focuses only on studies published after 2000
- Uses explicit, reproducible methods to search, select, and synthesize studies (Correct answer)
- Is written by a single authoritative expert
- Includes only experimental studies
Correct answer: Uses explicit, reproducible methods to search, select, and synthesize studies
Systematic reviews follow pre-specified, transparent protocols for searching and evaluating literature, reducing bias compared to informal narrative reviews.
Question 5: A student guitarist records daily practice sessions and logs perceived difficulty ratings. This approach to self-monitoring most closely resembles which research tool?
- Structured clinical interview
- Experience sampling / ecological momentary assessment (Correct answer)
- Retrospective survey
- Blind performance rating
Correct answer: Experience sampling / ecological momentary assessment
Experience sampling or ecological momentary assessment captures real-time data about experiences in everyday contexts, minimizing recall bias.
Question 6: Which statistical threshold (alpha level) is most conventionally used to determine significance in music performance research?
- p < 0.10
- p < 0.05 (Correct answer)
- p < 0.50
- p < 0.001 only
Correct answer: p < 0.05
The conventional significance threshold in most behavioral and music research is p < 0.05, meaning less than a 5% probability the result occurred by chance.
Question 7: When a guitar teacher says she uses 'evidence-based practice,' she should be able to demonstrate that her instructional decisions are informed by:
- Only her own performance experience
- Peer-reviewed research, clinical expertise, and student needs (Correct answer)
- The most popular YouTube tutorials
- Traditional methods passed down by her own teacher
Correct answer: Peer-reviewed research, clinical expertise, and student needs
Evidence-based practice integrates the best available research evidence with professional expertise and the individual learner's context and preferences.
