Data Analysis Expert
Challenge the national technical qualification! 🏆

Big data analyst?

Planning big data analysis based on understanding big data,
Performs big data collection, storage, processing, analysis and visualization
This is a certificate for verifying practitioners .

In order to secure the competitiveness of the country and companies, the demand for big data analysis experts is increasing. However, due to the shortage of supply compared to demand, it is difficult to secure manpower. Therefore, the government launched the National Technology Big Data Analysis Engineer Certification, a national technical qualification that systematically verifies capabilities along with the training of big data analysis experts.

In 2025, the 10th and 11th regular exams will be held, and the difficulty of the exams increases with each successive exam, so in-depth study is required. This lecture summarizes the basics and core contents of three subjects: Python, Pandas, data processing, and machine learning .


Only the essential content to pass the exam!! 👌

This course is a course to learn about the programming language Python and the Pandas, Scikit-Learn, statsmodels, and scipy libraries. It is a course that can prepare for the 1st, 2nd, and 3rd tasks of the Big Data Analysis Engineer practical exam. Since it is a practical exam that cannot be solved by simple memorization , explanations are provided centered on examples that can help with various applications .

Pandas

  • You can learn by following the process from importing to preprocessing and analyzing using 4 files.
  • The explanations are repeated according to the level of difficulty so that you can learn it naturally .
  • Covers various data preprocessing techniques required for machine learning.

Scikit-Learn, statsmodels

  • Understand the concepts of machine learning by using simple training data and performing simple modeling.
  • We cover examples of modeling using past Big Data Analysis Engineer questions and data from Kaggle.
  • Task 2, 3 types teach you memorization methods and flow so that you can prepare only for the types that will appear on the exam .
  • ✅ You can practice by solving past exam questions to get a high score.

📖 Big Data Analysis Engineer Exam Guide

  • Integrated (written and performance) 180-minute test
  • Big data analysis practice: data collection, data preprocessing, data model construction/evaluation
  • Passing is 60 points or more out of 100
  • 2025 Application/Examination Date: 10th (May 19-May 23 / June 21 (Sat) , 11th ( October 27-October 31 / November 29 (Sat) )
  • Please refer to the Korea Data Industry Promotion Agency website for detailed application qualifications and passing criteria.

Learning Support 📚

* Quiz will be held every day starting April 16th for the 10th test.
* We operate an open QnA KakaoTalk room to help you resolve any difficulties you may have during your training.

What you'll learn 📚

STEP 1. Know Python

This course focuses on acquiring Python language skills by learning only the important contents at a level for exam preparation for beginners who are not familiar with Python.

STEP 2. Data processing with Pandas

Learn the basics of Pandas, a Python library for handling data. Type 1 of the task-based exam understands the types of data processing that can be presented from various perspectives, and understands data processing methods by directly following the problem solving.

STEP 3. Machine Learning

In preparation for the Type 2 practical exam, learn about the overall structure and techniques of machine learning using sklearn. Learn how to create and evaluate machine learning regression and classification models, and solve past and highly likely questions.


STEP 4. Statistical Testing

To prepare for the Type 3 practical exam, we will learn about the interpretation of linear models and parametric/nonparametric tests using statsmodels and scipy.

STEP 5. Solving past exam questions

We will solve past exam questions from the 2nd to the 9th exam to help you prepare for the actual exam.
Episode 9 is scheduled to be uploaded on April 7th.

Q&A 💬

Q. How many times can I take the practical exam after passing the written exam?

After passing the written exam, you have the opportunity to take the practical exam for two years. Since there are two exams per year, there are a total of four opportunities to take the exam. Please note that this is a national technical qualification and you must check if you are qualified to take the exam.

Q. How long should I study?

The learning period will vary from person to person. And if you learn without any concept of programming, it will take more time. I think it would be good to set aside about 2~3 months and make time to input and interpret code repeatedly every day. In particular, the learning about Pandas and ML is prepared to the extent that you can use it, so you may feel that there is a lot of content. It would be good to learn while asking questions, and you also need to memorize the actual code right before the exam.
