2. Identify gaps | What questions remain unanswered? |
3. Primary research | Fill gaps with original research |
4. Integrate | Combine insights from both sources |
PART D: QUALITATIVE VS QUANTITATIVE RESEARCH
Definitions
Type | Definition |
|---|---|
Quantitative | Research that collects numerical data that can be statistically analysed |
Qualitative | Research that explores attitudes, behaviours, and experiences through non-numerical data |
Comparison
Aspect | Quantitative | Qualitative |
|---|---|---|
Data type | Numbers, statistics | Words, images, observations |
Sample size | Large | Small |
Questions | How many? How much? What %? | Why? How? What does it mean? |
Methods | Surveys, experiments, analytics | Interviews, focus groups, observation |
Analysis | Statistical | Thematic, interpretive |
Results | Generalisable | Not generalisable |
Depth | Broad, shallow | Narrow, deep |
Structure | Structured, standardised | Flexible, exploratory |
Objectivity | More objective | More subjective |
Reliability | High (if done well) | Lower (interpretation varies) |
Validity | May miss meaning | Rich understanding |
When to Use Each
Use Quantitative When... | Use Qualitative When... |
|---|---|
Need statistical evidence | Need to understand "why" |
Testing hypotheses | Exploring new areas |
Measuring market size | Understanding attitudes |
Tracking trends | Developing new products |
Large sample needed | Depth more important than breadth |
Comparing segments | Understanding customer experience |
Need precise numbers | Generating ideas |
Mixed Methods
Combining both approaches often provides the best insights:
Approach | Description |
|---|---|
Sequential | Qualitative first to explore, then quantitative to measure |
Concurrent | Both conducted at same time |
Explanatory | Quantitative first, qualitative to explain results |
PART E: SAMPLING
Definition
Sampling is the process of selecting a subset of a population to participate in research, from which conclusions about the whole population can be drawn.
Key Terms
Term | Definition |
|---|---|
Population | The entire group the research is about |
Sample | The subset selected to participate |
Sample size | Number of participants in the sample |
Sampling frame | List from which sample is drawn |
Sampling error | Difference between sample and population |
Why Sample?
Reason | Explanation |
|---|---|
Cost | Cheaper than researching entire population |
Time | Faster to complete |
Practicality | Often impossible to reach everyone |
Quality | Can focus resources on fewer respondents |
Sampling Methods
1. Quota Sampling
Definition: The researcher sets quotas for different categories (e.g., age, gender) and samples until each quota is filled. Selection within quotas is non-random.
Example: Interview 50 men and 50 women; 25 aged 18-30, 25 aged 31-50, 25 aged 51-70, 25 aged 70+.
Advantages | Disadvantages |
|---|---|
Ensures representation of subgroups | Non-random selection within quotas |
Quick to implement | Selection bias possible |
Cheap | Not statistically representative |
No sampling frame needed | Results not generalisable |
Guarantees key segments included | Quotas may not reflect population |
Best for: Quick, low-cost research needing specific group representation.
2. Random Sampling
Definition: Every member of the population has an equal, known chance of being selected. Selection is entirely by chance.
Also called: Simple random sampling, probability sampling
Methods:
Random number generator
Lottery/draw from hat
Systematic (every nth person)
Advantages | Disadvantages |
|---|---|
Statistically valid | Requires complete sampling frame |
Results generalisable | Can be expensive |
Eliminates selection bias | May miss key subgroups by chance |
Allows statistical inference | Time-consuming |
Most representative | May be impractical |
Best for: Large-scale research needing statistical validity.
3. Convenience Sampling
Definition: Selecting participants who are easily accessible and willing to participate — the most convenient option.
Also called: Opportunity sampling, accidental sampling
Examples:
Stopping shoppers in a mall
Surveying students in a class
Using social media followers
Advantages | Disadvantages |
|---|---|
Very quick | Not representative |
Very cheap | Highly biased |
Easy to conduct | Results not generalisable |
Good for initial exploration | Over-represents accessible groups |
Useful when time-limited | May miss important segments |
Best for: Exploratory research, pilot studies, when resources very limited.
4. Stratified Sampling
Definition: The population is divided into distinct subgroups (strata) and random samples are taken from each stratum in proportion to their size.
Example: If population is 60% female and 40% male, sample 60 women and 40 men from a sample of 100.
Advantages | Disadvantages |
|---|---|
Ensures representation of all strata | Requires knowledge of population |
More precise than simple random | More complex to implement |
Efficient for heterogeneous populations | Need sampling frame for each stratum |
Reduces sampling error | Time-consuming |
Best for: When population has distinct subgroups that need representation.
5. Cluster Sampling
Definition: The population is divided into clusters (often geographic), and entire clusters are randomly selected for research.
Example: Randomly select 10 schools from a city, then survey all students in those schools.
Advantages | Disadvantages |
|---|---|
Cost-effective | Higher sampling error |
Practical for large, spread populations | Clusters may be similar internally |
No complete population list needed | Less precise than other methods |
Best for: Large geographic areas; when complete population list unavailable.
Sampling Methods — Summary
Method | Type | How It Works | Best For |
|---|---|---|---|
Random | Probability | Everyone has equal chance | Statistical validity |
Stratified | Probability | Random within subgroups | Ensuring subgroup representation |
Cluster | Probability | Random selection of groups | Large, dispersed populations |
Quota | Non-probability | Fill quotas for categories | Quick, specific segments |
Convenience | Non-probability | Most accessible participants | Exploratory, limited resources |
Sample Size Considerations
Factor | Effect on Sample Size |
|---|---|
Population size | Larger population may need larger sample |
Desired precision | More precision = larger sample |
Confidence level | Higher confidence = larger sample |
Variability | More varied population = larger sample |
Budget | Constrains sample size |
Time | Constrains sample size |
Research purpose | Statistical testing needs larger samples |
PART F: ETHICAL CONSIDERATIONS IN MARKET RESEARCH
Key Ethical Issues
Issue | Considerations |
|---|---|
Informed consent | Participants must know what they're agreeing to |
Confidentiality | Protect respondent identity and data |
Privacy | Respect personal boundaries |
Honesty | Don't deceive participants about purpose |
Data protection | Comply with laws (GDPR, etc.) |
