Cultural Notes on Data Analysis in Korea
In Korean academic and business environments, data-driven decision-making is highly valued. Presenting statistical results, like those from regression analysis, requires clarity and precision.
Familiarity with specific statistical software like SPSS or R is common, and discussions often involve terminology related to these tools. Knowing the Korean terms for functions or outputs can be beneficial.
When presenting analysis results, clearly stating the hypothesis, methods (분석 방법 – bun-seok bang-beop), key findings (주요 결과 – ju-yo gyeol-gwa), and interpretations (해석 – hae-seok) is standard practice.
The field of data science (데이터 과학 – de-i-teo gwa-hak) is rapidly growing in Korea, increasing the importance and frequency of discussions involving statistical modeling techniques like regression analysis across various industries.
