The Purposes of Market Research (Cambridge (CIE) A Level Business): Revision Note
Exam code: 9609
The main features of a market
Market size
Market size is the value or volume of sales of all businesses within a market
It can be measured by sales volume or sales value
E.g. in 2024, the UK vinyl record market was worth £159m, with 5.9m units sold, the highest annual level since 1990
The total size of a market will be a key factor in determining whether it is worth a business entering and competing within it
A larger market size suggests more potential customers, which means greater opportunities to sell products and earn revenue
Knowing the size of the market helps businesses judge whether there is room to grow or if the market is already saturated
Investors are more likely to support a business operating in a large or growing market, as it promises better returns
Market growth
The speed of growth of a market is another key factor to consider when weighing up whether to enter and compete within it
More customers are entering the market, which makes it easier for new or smaller businesses to gain sales without taking customers from rivals
When demand is rising, competition tends to be less aggressive because most firms can grow at the same time
This reduces the pressure to lower prices or fight over market share
A growing market is a sign that it has long-term potential
Businesses can plan for future expansion, build customer loyalty early and benefit from rising demand
Market growth is expressed as a percentage and calculated using the formula
Worked Example
Supermarket sales data shows shoppers are putting more plant-based milk in their baskets. In the year to February 2025, market sales were up 2.1%. Oat milk sales have grown particularly strongly. Annual sales reached £275m in 2024, up from £155m in 2020.
Calculate the percentage increase in the size of the UK oat milk market since 2020.
[2]
Step 1: Subtract 2020 sales from 2024 sales to determine the increase
(1)
Step 2: Divide the difference by 2020 sales
Step 3: Multiply the outcome by 100 to determine market growth

Competitors
The number and nature of rivals in a market is a key consideration for a business looking to enter and compete within a market
The level of competition affects pricing and profitability
If there are many competitors, prices are often lower because businesses compete to attract customers. This can reduce profit margins.
E.g. A new café in a street full of other cafés might struggle to charge higher prices or attract loyal customers.
Many rivals makes It harder to stand out
In markets with many similar businesses, it can be difficult to offer something different or unique.
E.g. A new clothing brand may find it difficult to stand out in the fast fashion market unless it offers something distinctive, like sustainable materials or custom designs
Strong, well-established competitors are hard to challenge
If existing businesses have strong brands, loyal customers or economies of scale, it can be difficult for new firms to compete.
E.g. A small soft drink company would find it very hard to take market share from Coca-Cola or Pepsi
Market research, customer characteristics, profiles, wants and needs
Marketing research is the process of finding out information about the market in which a business operates by collecting, presenting and analysing information about customer characteristics, their profiles and their wants and needs
Market research, consumer characteristics and profiles
Market research gathers data directly from potential and existing customers using methods such as surveys, interviews, focus groups, and observation
This helps businesses learn about who their customers are and what they want.
It can identify consumer characteristics such as:
Age
Gender
Income level
Occupation
Location
Lifestyle, tastes and preferences
This information is then used to create customer profiles, which are detailed descriptions of target customers
E.g. A customer profile might describe a typical buyer as a 30-year-old, urban, environmentally conscious professional who shops online and prefers sustainable products
