Market Research

Sampling & reliability

Aims:

To recap intro to Market research – market research methods, qualitative & quantitative methods.

To understand the different types of samples available in market research.

To understand the factors influencing the choice of sampling methods.

Recap last theory lesson

What is the difference between field and desk research?

Field = collecting new data direct from people Desk = collecting existing/printed data

What is the difference between qualitative and quantitative research?

Qualitative = personal opinion Quantitative data = statistical data - % results

Different types

of research methods include

Accounts

Consumer panels

Experiments

Government statistics

Group interviews

High street surveys

Internet results

Loyalty cards

Market research publications

Quantitative v Qualitative

Quantitative Research Qualitative Research

Based on opinions, attitudes, beliefs and intentions

Answers questions such as “why”? “Would?”, or “how?”

Aims to understand why customers behave in a certain way or how they may respond to a new product or service

Focus groups and interviews are common methods used to collect qualitative data

Concerned with data and addresses question such as “how many?”, “how often”, “who?”, “when?” and “where?”

Based on larger samples and is, therefore, more statistically valid

The main methods of obtaining quantitative data are the various forms of survey – i.e. telephone, postal, face-to-face and online.

Why do businesses need Market research?

Descriptive: To identify what’s happening in the market.

Predictive: To predict what’s likely to happening in the future.

Exploratory: To investigate new possibilities in a market.

Your task – take a business and identify one of each reasons for Market research

Descriptive: To identify what’s

happening in the market.

Predictive: To predict what’s likely to

happening in the future.

Exploratory: To investigate new

possibilities in a market.

Sampling

It is not possible to survey every possible customer, so market research needs to take a sample of the population.

Random sampling Quota sample Stratified sample Cluster sample

Random sampling

Each member of the sample is selected at random… like out of a hat… but today it uses ICT!

Methods: Pick every 50th off the electoral list. Send interviewer to their house Return twice if they are out!

What are the

benefits and problems?

Quota sample

This segments the population into groups that share specific characteristic.

Interviews are then asked to interview a set number within each segment.

E.G. interview 20% under 16’s; 15% 17 – 25; 25% 26 – 50 etc… What are the

benefits and problems?

Stratified sample

To only select those with key characteristics to suit the focus of the products.

To interview Swimmers for new swimwear, Equestrians for new jodhpurs!

What are the

benefits and problems?

Cluster sample

To send interviews into a few geographical areas.

E.g. To a few seaside resorts to research swimwear.

Sampling – Main Methods

Random sample

A random sample gives each member of a population an equal chance of being chosen. The main advantage of this is that bias is not introduced when the sample is chosen. However, a random sample also assumes that all members of the population are the same, which is rarely the case! The main drawback of random sampling for a start-up is the cost of the required sample size. Random sampling needs large sample sizes in order to achieve acceptable confidence levels.

Quota sample

Quota sampling involves the population being segmented (broken up) into groups that share specific characteristics. The research then focuses on a specific sample size (quota) chosen for each group.

Quota sampling can help market research focus more closely on the target customers or market segments. However, it takes more time than random sampling and is the sampling method most likely to result in bias.

Stratified sample

Stratified samples are used when the research wants to provide insights into specific market segments or customer groups. Once the target group is selected the sample is chosen at random from that group.

A stratified sample still has the benefit of being random (i.e. low bias) and is not as expensive or difficult to obtain as a full random sample.

Factors affecting sample size

Finance and cost

Important . Market research should be low cost, or even better, free!

Type of product

If the start-up is offering an existing product or service, there may be lots of secondary research already available. By contrast, a new product is less likely to have secondary data available

Level of risk The newer the product and the greater the investment prior to launch – the greater the risk. If the start-up is investing significantly upfront and there is a high chance of failure, this increases the need for effective primary research. In such a situation, there is a case for choosing a random sample, backed up by additional quota or stratified samples.

Target market

If the start-up’s product is targeted at a specific segment (e.g. geographical, income) then it is easier to target primary research. If the business can identify the target customers, then it is usually more appropriate to conduct research using a stratified sample.

Reliability of research.

Human behaviour – in answers given & a true understanding of their reasons behind their actions.

Sampling & bias – are the interviewees representative?
