3.2 Understanding market and customers
Market research
Definition: the systematic process of collecting, analysing, and interpreting
information about a market, including potential customers and competitors
– collecting data about a market

Quantitative data: numerical information or data that can be expressed as a
value
Qualitative data: non-numerical information that provides insights into the
qualities, characteristics or attributes of a subject

Benefits
– Reduces the risk of making a poor decision
– Helps businesses reach customers before their rivals
– Helps a market-oriented business identify their customers’ needs

Drawbacks
– Research takes time and resources
– depends on how well data is interpreted
– Conditions may change if the market is dynamic



Primary research

a specific research purpose

Examples of primary market research
– Surveys / questionnaires
– Focus groups
– Social media data
– Observations

Benefits
– specific to the business
– meets prices needs of the business
– can discover information that no other business has access to

Drawbacks
– needs specialist knowledge to set up and carry out
– can be expensive
– often time-consuming
– may not be comprehensive enough to make an informed decision: not

, –
enough information


Secondary research
Definition: research which uses data that has already been collected

Benefits
– cheaper
– quick to access

Drawbacks
– not always in the format that the business wants —> not tailored to
specific businesses
– available to competitors
– may only partially answer the specific questions



Market mapping
Definition: the process of visually representing the positions of different
products or brands in a market based on specific criteria such as price and
quality




Benefits
– Easily spot a gap in the market
– Easy comparison from visual representation
– Useful for analysing competitors

their marketing mix
– Chooses two factors to focus on
– Encourages use of market research

Drawbacks

, – Ignores external factors
– Basic model —> only able to focus on two factors

○is based on company’s perspective
– Depends on reliability of market research
– A gap in the market doesn’t mean there is demand



Sampling
Definition: the process of selecting a subset from a larger population to
represent and analyse characteristics of the entire population

Benefits
– removes impracticability of sampling entire population
– using sampling before marketing decisions can reduce risks and costs
– is flexible and relatively quick

Drawbacks
– sample might be unrepresentative of the population —> leading to
incorrect conclusions
– risk of bias in research questions
– less useful in market segments where customer tastes and
preferences are changing frequently (dynamic markets)

Random sampling
Definition: involves selecting individuals entirely by chance, where each
member of the population has an equal chance of being chosen

Benefits:
– reduces bias, as every member has an equal probability of inclusion
– simple to conduct

Drawbacks:
– may not represent certain subgroups adequately
– chance variations can lead to a less accurate representation of the
population

Stratified sampling
Definition: dividing the population into subgroups (strata) based on certain
characteristics, then randomly samples from each stratum

Benefits:
– ensure representation from all relevant subgroups
– increased precision compared to simple random sampling

Drawbacks:
