To give this some more context here is little explanation about this survey.
It is form years back when SNSD and Kara used to rank on this thing but I think the survey method is still the same.
It's a big annual survey about celebrities.
The survey is done in Tokyo metro area, with stratified sampling. Total of 4400 people.
1100 people each from Tokyo, Chiba, Saitama and Kanagawa.
Each 1100 group is made up from subgroups depending on ag: the youngest subgroup being 100 people 10-14 years old and the oldest subgroup being 100 people 60-69 years old.
Each subgroup is 50% men and 50% women.
The survey includes 1250 celebrities, and the person taking the survey is answering the same questions on all of these.
The question on awareness has 3 options for answer:
#1 I know and recognize this celebrity
#2 I have heard the name but don't recognize the celebrity
#3 I don't know this celebrity at all
IF you answer with #1 on the awareness question saying that you recognize the celebrity, then you answer the followup question about if you ere interested in new work by that celebrity:
I'm very interested
I'm interested
I'm not really interested
I'm not interested at all.
The people who answered I'm very interested or I'm interested are counted as interested people.
So in Twice case out all people surveyed 38% answered "I know and recognize this celebrity" and out of those people 68.5% of them answered:
I'm very interested
I'm interested
to the follow up question about interest.
Meaning the overall interest for Twice out of all people surveyed was that 26%.
