Try these sample questions to review concepts for the Social Survey Analyst Grade 2 (사회조사분석사 2급) exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.
1In scientific social research methodology, which error occurs when an empirical finding observed at an aggregate group level is improperly inferred to hold true for individual members of that group?
2In the process of operationalization (조작적 정의), which operational step directly converts an abstract theoretical concept into observable and measurable empirical indicators?

Confirm exam requirements, fees, and policies with the official exam sponsor.
Subject 1: Survey Methodology and Design (조사방법과 설계)
Covers survey planning and formulation of research questions, exploratory vs descriptive vs causal research designs, probability sampling (simple random, systematic, stratified, cluster) and non-probability sampling (convenience, purposive, quota, snowball), sample size determination formulas, sampling error, questionnaire item writing rules, response scale formatting, and qualitative research methodologies including focus group interviews (FGI) and in-depth interviews.
Subject 2: Survey Management and Data Processing (조사관리와 자료처리)
Covers primary data collection methods (face-to-face interviews, telephone surveys, online/web surveys, mail surveys, and observational methods), fieldwork administration and interviewer training, non-response management and non-sampling errors, secondary data analysis, levels of measurement (nominal, ordinal, interval, ratio), scale types (Likert, Thurstone, Guttman, semantic differential), and measurement validity (content, criterion-related, construct) and reliability (test-retest, split-half, Cronbach's alpha).
Subject 3: Statistical Analysis and Utilization (통계분석과 활용)
Covers descriptive statistics (mean, median, mode, variance, standard deviation, IQR, skewness, and kurtosis), probability theories and distributions (binomial, Poisson, normal, standard normal z, Student's t, chi-square, F), sampling distributions and the central limit theorem, statistical estimation and confidence intervals, hypothesis testing principles (Type I and Type II errors, p-values), one-sample/independent/paired t-tests, one-way and two-way ANOVA, Pearson and Spearman correlation, simple and multiple linear regression, and chi-square tests.

Social Survey Analyst Grade 2 (사회조사분석사 2급): Suggested Study Strategy
Frequently Asked Questions
What is Social Survey Analyst Grade 2 (사회조사분석사 2급) and which bodies administer it?
Social Survey Analyst Grade 2 is a South Korean National Technical Qualification (국가기술자격) overseen by the Ministry of Data and Statistics (국가데이터처, which replaced Statistics Korea/통계청 on 1 October 2025) and administered by the Human Resources Development Service of Korea (한국산업인력공단 / HRD Korea) through Q-Net under JM code 9521. It certifies practical competency in research planning, questionnaire design, sampling, and statistical data processing.
What is the examination structure and passing criteria for the written test?
The written test comprises 100 four-option multiple-choice questions across three subjects: 1. Survey Methodology and Design (30 questions), 2. Survey Management and Data Processing (30 questions), and 3. Statistical Analysis and Utilization (40 questions). The time limit is 150 minutes. Passing requires scoring at least 40% in every individual subject (과락 방지) and achieving an overall average of 60% or higher.
What does the second-stage practical examination involve?
The practical examination (사회조사분석실무) is a composite assessment consisting of a 2-hour descriptive written test (필답형, 60 points) evaluating survey design critique and questionnaire drafting, and a 2-hour software-based working test (작업형, 40 points) requiring data cleaning and statistical modeling using SPSS, SAS, or R. Passing requires an aggregate score of 60 out of 100.
Are there any eligibility restrictions or prerequisites for Grade 2?
No. Unlike Grade 1 (which requires holding Grade 2 plus 2 years of field experience, or 3 years of qualifying practice), Social Survey Analyst Grade 2 has no academic, age, or experience requirements. Anyone can register and sit for the exam.
What statistical formulas and calculations are tested in Subject 3?
Subject 3 tests calculations of sample mean, variance, standard deviation, standard error, z-scores, confidence intervals for population means and proportions, t-statistics for two-sample tests, F-ratios in ANOVA tables, sample correlation coefficients, and least-squares regression slope and intercept formulas.
Why is this OpenExamPrep question bank presented in English?
While the official examination is delivered in Korean, this bank provides a rigorous English-language study adaptation designed for international researchers, bilingual analytics professionals, and students. Key Korean terminology (e.g., 계통표본추출, 층화표본추출, 신뢰도, 타당도, 제1종 오류, 유의확률) is preserved alongside precise English definitions. This is an independent English-language study adaptation, not an official translation, not a simulation of the Korean-language CBT environment, and not a substitute for the second-stage practical examination (사회조사실무), which is assessed by a 필답형 written paper and a 작업형 exercise carried out in a statistical package.
