The panel is a representative sample of the internet user population. KoreanClick panel is composed of internet users between the ages of 7 and 65 residing in Korea. The composition takes into account the gender, age and regional demographics of the Internet users based on population estimation.
The panel selection is made by random sampling(RDD, ABS, MMS, Recommendation etc.). Interference from outside that may affect panel selection and biased panel selection, such as open advertisement of panel recruiting and selecting panels from a specific portal site's members, are discouraged.
The person in charge of panel selection randomly phones the candidates among the estimated population to solicit panel participation. Those who show interest are invited to join the KoreanClick panel. However, those who purposely volunteer to participate in the panel solely for the sake of compensation are excluded from the recruiting.
