Quantitative Data vs. Qualitative Data (11.3)

Chapter 11 - Market Research

Lesson Objective: To understand the differences between quantitative and qualitative data

 

Primary and Secondary Market Research are essentially different:


Let's dive in more details on those two types of research/data:

  • Primary Research: collecting first-hand data that serves the research purpose:


Primary Research can be of two types:

- Quantitative Research, which produces numerical results and can be presented as tables, charts, and analyzed through statistics (33% of students don't deliver their homework);

- Qualitative Research, focused on gathering opinions and factors influencing purchase behavior and not numerical data.



There are mostly four methods of Primary of Market Research:

  1. Focus Groups

  2. Observation

  3. Test Market

  4. Interviews

1. Focus Groups: meetings with 10-15 potential or actual customers to discuss opinions on new products, packaging, brands, ads, etc.


- Good source of qualitative data;

- Time-consuming as many rounds are needed;

- No numerical data is generated.



2. Observation: observing customers as they shop and/or consume products in their 'natural environments'.


- Customers are behaving naturally and therefore findings are accurate;

- Time-consuming and expensive as it requires trained researchers to conduct;

- Observers do not interact with customers which doesn't give the possibility for asking questions.



3. Test Market: producing and selling products at a limited quantity in a selected location:

- To collect feedback from customers and improve before the mass launch;

- Increases the chances of a successful launch of the product;

- Time-consuming and allows competitors to catch up with similar products;

- It's expensive to do since the product needs to be made and sold for testing.


4. Surveys: which can be of different types, some of which will generate qualitative data and some will generate quantitative data:

  • Interviews - Qualitative Data:


- Asking and explaining open-ended questions;

- Collecting and recording answers;


- Expensive as it's a one-by-one method and requires multiple rounds;

- Can be misleading if the interviewer is not skilled for the job.



  • Online Surveys - Quantitative Data: questionnaires are sent online to people (email, social media, etc.) with close-ended questions (multiple-choice or scale questions):


- Allows businesses to research people in different geographical areas at the same time;

- Inexpensive;

- Can be instantly collected and analyzed;

- It can have a low-response rate when receivers tag it as 'junk' and ignore them.



  • Mail Surveys - Quantitative Data: questionnaires sent to peoples' homes to be answered and returned:


- Allows for gathering data from multiple geographical areas at the same time;


- More expensive than online surveys but less expensive than interviews;


- It oftentimes have a low-response rate as people tend to ignore them ('junk mail').
