Research Methods: A Comprehensive Guide to Data Collection Techniques
Research Methods: Data Collection Techniques
Qualitative vs. Quantitative Research
Traditional vs. Online Focus Groups
Traditional focus groups involve 8-12 participants, while online groups have 4-6 due to platform limitations. Online groups offer advantages like increased honesty, faster turnaround, and lower costs. Traditional groups allow for observing non-verbal cues and using physical stimuli. Moderator skills are crucial in both settings.
Direct vs. Indirect Research
Direct research openly reveals the research purpose, while indirect techniques conceal it until the end. Direct methods are transparent, while indirect methods minimize bias.
Depth Interviews
Advantages
- Uncover underlying motivations
- Explore sensitive topics
- Easy to schedule
Disadvantages
- Lack of representativeness
- Interviewer bias
- Time-consuming analysis
- Less cost-effective than focus groups
Projective Techniques
Advantages
- Elicit subconscious thoughts
- Uncover hidden motives
Disadvantages
- Lack of representativeness
- Messy data prone to bias
- Requires skilled interpreters
Survey Methods
Face-to-Face Surveys
In-Home Surveys
- Advantages: Physical interaction, non-verbal communication, trust-building
- Disadvantages: Expensive, slow data collection, potential refusals, interviewer bias
Mall Intercept Surveys
- Advantages: Easy access to target audience, interviewer efficiency, controlled environment
- Disadvantages: Potential for bias, limited sample representativeness
Computer-Assisted Personal Interviews (CAP)
- Advantages: Cost-effective, reduced interviewer bias, benefits of CATI
- Disadvantages: Requires technology and trained interviewers
Mail Surveys
- Advantages: Cost-effective, anonymity for respondents
- Disadvantages: Low response rates, lack of interaction, slow data collection
Online Surveys
- Advantages: No interviewers, potential for product interaction, rapid data collection
- Disadvantages: Risk of bias, lack of control over environment, need for attention checks
Question Types
Unstructured Questions
- Advantages: Suitable for exploratory research, foster trust, build rapport
- Disadvantages: Interviewer bias, time-consuming, subjective coding
Structured Questions
- Advantages: Reduced interviewer bias, faster response times, easier coding
- Disadvantages: Limited options for respondents, potential for incomplete data
Types of Structured Questions
Comparative Scaling
- Paired Comparison: Simple and fast, but not suitable for predicting purchase intention
- Rank Order: Efficient way to order preferences
- Constant Sum: Allows for understanding preference strength and segmentation
Non-Comparative Scaling
- Likert Scale: Measures agreement or disagreement on a 5-point scale
- Semantic Differential: Measures perception using bipolar adjectives on a 7-point scale
