Study Notes
Practical Research 2: Planning Data Collection
-
Importance of Data Collection:
- Data collection is crucial for research integrity, reducing errors, supporting informed decision-making, and saving time and resources.
- It's essential for justifying new ideas, changes, or innovations.
-
Sources of Data:
- Primary sources provide raw, first-hand information (e.g., interview transcripts, data).
- Secondary sources offer commentary or interpretation from other researchers (e.g., journal articles, reviews).
-
Data Collection Methods:
- Data collection tools are instruments varying by research design and methodological goals, aiming to collect credible evidence.
-
Quantitative Methods:
- Interviews: Structured (standard questions), semi-structured (open-ended discussion), and unstructured (informal conversation). Pros: in-depth information, flexibility, accuracy. Cons: time-consuming, costly.
- Questionnaires: A tool for gathering group data. Pros: large-scale administration, cost-effective, easy visualization. Cons: potential for dishonesty, unanswered questions.
- Observation: Complete/participant observer roles. Pros: direct data collection, accuracy in some cases. Cons: bias, expense, difficulty predicting value.
- Reporting: Recording/reporting data. Pros: decision-making, accessibility. Cons: potential for inaccurate information.
- Tests: Norm-referenced (comparing performance to a group) or criterion-referenced (measuring mastery). Pros: evaluating knowledge/skills. Cons: bias, possible dishonesty.
Quantitative Analysis
-
Descriptive Statistics:
- Summarize data (frequency, averages, spread). Crucial for simplification.
- Types: Frequency (counts, percentages); Central Tendency (mean, median, mode); Dispersion/Variation (range, variance, standard deviation); and Position (percentile, quartile).
-
Inferential Statistics:
- Draw conclusions beyond immediate data.
- Types: Linear regression (relationship between variables); Analysis of Variance (differences between means); Analysis of Covariance (impact of intervening variables); t-tests (statistical significance).
Hypothesis Testing
- Hypothesis: An educated guess about something testable.
- Null Hypothesis (H₀): Asserts no relationship between variables. Represented by H₀.
- Alternative Hypothesis (H₁): States that a relationship does exist. Represented often as H₁ or Ha (signifies less-than, greater-than, or not-equal).
Sample Research Design
-
Quasi-Experimental Design is appropriate for studies like this, which measure change in response to an intervention.
-
Locale and Population: Specifies the location and characteristics of the study population.
-
Instrumentation: Describes the tools/measures employed in data collection.
-
Data Analysis: Discusses appropriate statistical methods and interprets results. Includes calculations like Kuder-Richardson Formula 20 for reliability and determining appropriate indices of difficulty.
