Study Notes
Data Analysis
- Data preparation: Ensure data is clean, complete, and in suitable format for analysis
- Descriptive statistics: Calculate means, medians, modes, and standard deviations to understand data distribution
- Inferential statistics: Apply statistical tests to draw conclusions about the population based on sample data
- Data visualization: Use plots and graphs to visualize data and identify patterns
Result Interpretation
- Identify significant findings: Determine which results are statistically significant (p-value < α) and worth discussing
- Evaluate results in context: Consider research questions, literature reviews, and study objectives when interpreting results
- Avoid over-interpretation: Be cautious when generalizing results to broader populations or making causal inferences
Conclusion Drawing
- State main findings: Clearly summarize key results and implications
- Relate to research questions: Address how results answer or fail to answer research questions
- Implications and recommendations: Discuss practical applications and potential avenues for future research
- Limitations and future directions: Acknowledge study limitations and suggest areas for improvement
Hypothesis Testing
- State null and alternative hypotheses: Clearly define hypotheses to be tested
- Specify α-level: Determine the significance level (e.g., 0.05) for rejecting the null hypothesis
- Interpret p-values: Compare p-values to α-level to determine significance
- Report effect sizes: Calculate and report effect sizes (e.g., Cohen's d) to provide context
Study Limitations
- Identify potential biases: Acknowledge sources of bias and their potential impact on results
- Discuss generalizability: Consider the extent to which results can be applied to other populations or contexts
- Address methodological limitations: Describe any methodological constraints or limitations
- Suggest avenues for future research: Identify areas for improvement and potential avenues for future study
