Q

Why should we do a quantitative market research?

A

Because we don’t know:

  1. what customer actually need
  2. what’s on their mind or how their situation is changing
  3. what they are unhappy about
  4. what is driving happyness
  5. How many customers of different types there are out there?
  6. How customers select a vendor, search for information, decide where to shop
  7. What drives the choice of one product over another
  8. How much they are willing to pay
  9. How many buy at this price

Q

What is a sample?

A

A selection from the population

17
Q

What is a sample frame?

18
Q

what different sample types are there?

A
  1. Probability samples
  2. Non- probability samples
  3. Census
19
Q

What is a probability sample?

A

The probability for selection of each individual is known

Statistical methods assume probability samples

— simple random sampling
— systematic sampling
— stratified random sampling
— cluster sampling
— multistage sampling

— large number of respondents (+100)

20
Q

what is a non-probability sample?

A

The researches uses the judgement to select respondents suitable for the purpose

— quota samling
— dimensional sampling
— convenience sampling
— purposive sampling
— snowball sampling
21
Q

What is a census sample?

A

The whole population is surveyed

Financially viable when the population is very small

22
Q

Describe the process of questionnaire design!

A
  1. Generate list of potential topics and kind of information to be collected
  2. Construct a first draft
    —> including actual questions and answer categories
    —> re-use own questions or from existing questionnaires
  3. Put it aside for a few days, then revise
  4. Circulate for the comments and critique
  5. produce another draft
  6. circulate comments
  7. produce final draft
  8. pre-test
  9. produce final version
23
Q

Advice for questionnaire in general

A
  1. maximize the reward and minimize the costs for responding
  2. shorter is better
  3. cluster contents and seek natural flow
  4. place demographics and classification data last
  5. starting with relevant & interesting questions
  6. professional appearance
24
Q

Advice for question phrasing in the questionnaire

A
  1. keep it simple
  2. be specific
  3. ask mostly closed-ended questions
  4. always ask some open-ended questions
  5. mnimize demands on memory
  6. match questions to how the market works
  7. avoid loaded questions
25
Q

Advice regarding answer categories in questionnaires?

A
  1. use the right number of answer of answer categories
    —> yes-no is sometimes enough

2.distinguish between bipolar and unipolar responses
—> BIPOLAR: qualitative answer categories
—> UNIPOLAR: quantitative from 0-100% e.g.

  1. attend to the interaction of the answer categories
  2. Beware of including don’t know and not applicable
  3. prefer ratings over rankings
26
Q

What different types of question are there?

A
  1. categorization
    B2C: age, gender, income, education, current brand
    B2B: employees, turnover, role in company
  2. Descriptive questions
    —> How often do you use our product
    —>what is the frequency of product X
  3. Rating scales
    —> how satisfied are you with our product’s performance
27
Q

Create a small questioner to understand customer needs of a industrial forklift!

A

DEMOGRAPHICS:
1. what is the turnover of your company
< 10 MEUR, 10-100 MEUR, >100 MEUR>

  1. How many employees do you have?
    < 100, 100-500, 500-500, >5000>

DESCRIPTIVE:
3. What is the average daily driving distance?

  1. Maximum shelf height

5 current brand

RATING:
The ergonomics of forklifts is not affecting pain in the body
< strongly disagree, disagree, agree, strongly agree>
It doesn’t matter if we have different types of brands of the fork lifter
—-

28
Q

How do you decide on sample size and source?

A
  1. what levels of confidence and precision do you want from your study
  2. how many respondents are needed to reach desired levels of confidence and precision?
  3. Given number of responses, what can be claimed about confidence level and precision?
29
Q

Formula for computing sample size N?

A

N=Z^2*variance/ precision^2

Z= confidence level= how likely would be to get the same difference by chance alone if there really is no difference in the population between categories represented by your group

Variance
= the variance in the population of the quantity to be estimated
= the average of the squared deviations of individual scores from the mean

Precision= the decision maker’s tolerable margin of error (compare with confidence interval)

35

Conclusions with regards to surveys?

A
  1. easy and cheap to create and distribute

  3. Surveys are an important tool for:
    —> product planners
    —> guiding improvement of existing products
    —> less applicable on completely new products
  4. Statistical significance of findings requires
    —> good questionnaire design
    —> large number of properly sampled responses
