Study Notes
Research Techniques
- Factor Analysis: Used for data reduction by identifying important variables and eliminating unimportant ones.
- Multiple Regression Analysis: Applies when independent variables need to explain or predict a dependent variable.
- Cluster Analysis: Utilized for grouping respondents based on preferences and demographics (not covered in the current course).
Research Locale
- Describe the study's location with supporting maps.
- Include a map of the Philippines and a local map highlighting the specific study area.
Sampling Plan
- Population and Sample: Choose an appropriate sample size, typically standardized by schools.
- Sample sizes vary: Undergraduate students often use a size of 100 (9.78% margin of error, 68.3% confidence) while graduate students typically require 377 (5% margin of error, 95% confidence).
- Raosoft sample calculator can help determine actual sample size and confirm margin of error and confidence level.
Sampling Techniques
- Simple Random Sampling: Draw respondents randomly; include a buffer of extra participants (20%) for non-participation.
- Stratified Random Sampling: Group respondents into strata based on natural population distributions, such as generational age.
Example of Stratified Sampling
- Population in Davao City based on age groups:
- Millennials: 575,152 (33.3%)
- Generation X: 248,714 (14.4%)
- Baby Boomers: 126,084 (7.3%)
- Sample distribution based on a total population of 949,950:
- Millennials: 228 respondents
- Generation X: 99 respondents
- Baby Boomers: 50 respondents
Poisson Distribution in Sampling
- A discrete distribution measuring the probability of events occurring in a timeframe.
- Random sampling can happen without a known population size, utilizing a non-sampling frame approach.
Research Methodology
- Research instruments should address all questions relevant to the study.
- Ethical Considerations: Ensure integrity by using original titles, conceptual frameworks, and instruments.
Ethical Issues to Avoid
- Respondents should be informed about the study's purpose, and their participation must be voluntary.
- Respondent data must remain confidential and anonymous, assigned only a number instead of a name.
- Plagiarism is strictly unethical and illegal, with severe penalties.
Data Gathering Tips
- Offer incentives to minimize rejection from potential respondents.
- Keep survey questionnaires concise (max five pages, 15 minutes to complete).
- Check for unanswered sections and ensure data completeness to avoid processing issues later.
- Once collected, encode data for analysis, typically using SPSS software.
Summary
- Research methodology outlines the systematic process of conducting an investigation, ensuring ethical integrity and employing appropriate sampling and data collection techniques.
