Even complex data can be seen at a glance in front of Tableau!

Conquer visualization of practical data, starting with a single drag and ending with a complete dashboard.

Visualization isn't just about difficult coding.

“Tableau visualization analysis” that implements high-end statistics with just a mouse drag!

“As soon as data trapped within tables becomes charts and dashboards, decision making is much faster.”

Start with a mouse, and the design is complete.

— Organize datasets that can be analyzed by linking multiple files and tables

— Use dimensions, measured values, and marks to express key indicators in an intuitive chart

— Use a time series forecasting model to immediately derive demand forecasting results for the next quarter

— Explore data distributions and segments with clustering and map visualization

Today is the last day of the analysis work that was tied to Excel and manual aggregation.

Don't chase data, be the 'architect' who completes the analysis system.

What is Tableau (Tableau)?

Tableau (Tableau) is the world's #1 business intelligence (BI) and data visualization tool.

It's a solution that allows anyone to build an intuitive dashboard by simply dragging and dropping without complicated coding or development knowledge.

Traditional spreadsheets are slow and require writing complex functions when analyzing large amounts of data.

Tableau quickly processes vast amounts of data and easily links various data sources.

Through interactive dashboards, hidden patterns and insights are identified at a glance, and data-driven decision-making across planning, marketing, and management is supported.

Stop wasting time analyzing data while struggling with Excel formulas!

Complete the data dominance of the top 1% practitioners with Tableau (Tableau)!

Features of a data visualization curriculum that can be completed in Tableau

It's a practical course that doesn't end with just creating a chart, but also completes a structure where the data speaks for itself.

1. 'Data preparation and connection' is the starting point for analysis

Complete an integrated dataset that eliminates preparation time for analysis by merging multiple files, sheets, and tables with Union and Join

2. 'Visualization principle design' showing context

Learn the operating principles of dimensions, measured values, and mark cards to design and configure your own charts that match data characteristics

3. 'Advanced analysis design' to capture signals in data

Complete analytical capabilities by directly implementing anomalies, correlation, time series prediction, and clustering with actual data

4. A “calculation and filter structure” that processes conditions without errors even when conditions change

Secure a system that accurately and automatically processes complex analysis conditions by understanding LOD, aggregate calculation, and filter priorities

5. 'Dynamic interaction' to communicate with users in real time

Use parameters and context filters to create a responsive reporting environment where decision makers respond as soon as they click the filter

Tableau is more than a tool to decorate data to look good.

It links scattered data to provide meaningful flow and practice-oriented analysis.

The collection is on Tableau.

Visualization is done by the mouse. Insights are mine.

What if you don't have time to look at insights by organizing the same table and redrawing the chart every time?

Cut down on organizing numbers and focus on insights in data!

I can confidently recommend it to people like this.

— A data beginner who knows Tableau is good but doesn't know where to start

— Office workers who need better tools because they are tired of Excel formula errors and repeated chart revisions

— People in charge of marketing, sales, planning, and operations who want to improve the persuasiveness of reports

— Business practitioners who want to develop data-driven decision-making skills

— Data non-majors who want to directly implement time series prediction and clustering without coding

Many people make charts, but different people design visualization structures.

Bring data to life and quickly uncover hidden insights with Tableau!

If you're only looking at data in a table, you're missing half of the insights.

Tableau turns key metrics into charts and dashboards with just drag-and-drop.

People who are good at showing data differ in how they report.

Spend less time creating charts and focus on finding insights!

Expected Questions Q&A

Q. Can beginners who are new to Tableau or data analysis take this course?

A. Yes, it is possible. Starting with the public installation of the Tableau desktop, this course is structured to learn basic concepts step by step, such as data connection, screen configuration, dimensions and measurement values, and the use of mark cards. Since it is learned through practice without complicated coding or statistical knowledge, such as creating charts or configuring dashboards, it is easy for first-time users to follow along.

Q. Can I take the course without the paid version of Tableau?

A. Yes, you can follow the exercises perfectly even with the free version. The beginning of the course includes steps to install Tableau Desktop Public together and set up the environment, so you can easily start learning with the free edition without paying a separate paid plan.

Q. Can I apply what I learned in the course directly to actual work?

A. Yes, this course is designed to be applied in practice. Practice is conducted based on key patterns directly used in actual business settings, such as 'Top N Top Analysis', 'K-means Automatic Clustering, 'and 'Time Series Predictive Analysis', and can be directly applied to actual work.

Please check before taking the course!

Since this is a practice-oriented course, it is a good idea to prepare a dual monitor or an extra device that can separate the lecture screen from the practice screen.

Also, since exercises are conducted based on Windows OS, we recommend taking courses in a Windows environment.
