Henri Coandă Airport: Travelers’ Experiences Revealed Through AI Conversations
How can technology enhance qualitative research? This question is answered by our recent study conducted with the help of an AI moderator. The moderator engaged in discussions with eight travelers about their experiences at Henri Coandă Airport in Bucharest. Each response revealed unique perspectives and highlighted both the strengths and weaknesses of this important Romanian […]
The Enigma of the Response Rate and How to Ensure Your Sample Doesn't Mislead You
A client asked me whether, with a 9% response rate, the resulting sample from surveying a customer database can still be considered representative. Situation: We have 1,400 unique contacts—customers who purchased online in 2023. The product is industrial, sold in large volumes but with low frequency, meaning customers return to purchase multiple times a year […]
Sampling Error in Estimating a Mean Value
When we sample a subset from a population instead of surveying the entire population, we aim for the measured value in the sample to be as close as possible to the true value in the population. When we say "value," we refer either to an average (e.g., the average height of individuals in the population) […]
8 Steps to design a sample - Part II
See the first three steps here. 4. What is the sampling frame? In essence, I am answering the question, "Where can I find the eligible respondent?" Bank employees can be reached via email, as the bank provides the contact list. Moreover, the bank has decided to invite all 2,800 employees, without applying any additional selection […]
8 Steps to design a sample - Part I
In the first two articles (1, 2), we focused on providing arguments for why sampling for a face-to-face (F2F) study in Romania is conducted following the rules/methodology of multi-stratified sampling combined with cluster sampling. Essentially, we answered the question, “How do I reach the respondent?” When I think about sampling, regardless of the study, we […]
Why you should combine multi-stratified random sampling with cluster sampling when conducting fieldwork in Romania. Part II
Now that we’ve established the context, I feel that we can return to our discussion about multi-stratification. Stratification is employed when you can divide the population into sub-groups which are heterogeneous, disjunctive. They do not overlap. This separation is very clear. It somewhat helps to break a large population or area into smaller, more manageable […]
Why you should combine multi-stratified random sampling with cluster sampling when conducting fieldwork in Romania. Part I
Stratified sampling and cluster sampling are two of the four types of probabilistic sampling. I suggest we combine them... it might seem weird, yet it really helps with managing random samples. One thing is certain regarding Romania and managing population data records – there is no possibility to draw a random sample of citizens from […]
