  • How to use kaggle notebook

  • Handling DataFrame and Series Type Data with pandas

  • Indexing data via pandas' loc

  • Calculating frequency with pandas value_counts

  • Visualizing frequency with seaborn countplot

  • Drawing a bar graph with seaborn barplot

  • Finding response frequency for multiple questions using pd.crosstab

  • Sorting data with sort_index() and sort_values()

  • How to use pandas filter

Kaggler's secrets revealed through data!
Now, take your first step into data analysis.

What are Kagglers around the world thinking?

Data Analyst , Data Scientist ,
I want to become a machine learning engineer ...
If you don't have anywhere to ask and have a lot of questions?!

Analyze it with data!

  • Maybe this will help you a little bit to solve your problem.
  • There are several choices for data beginners.

If you are wondering what to choose ?

The answer might be in the data!

Python vs. R vs. SQL

scikit-learn vs. TensorFlow

Matplotlib vs Seaborn vs Plotly vs ggplot

Jupyter vs. VS Code vs. PyCharm

AWS vs. MS Azure vs. GCP

Is it too late to start data science?

👉 What are the gender and age range of Kagglers?

Where do Kagglers mostly live and what occupations do they have?

👉 Data analyst? Scientist? Machine learning engineer? Programmer?

What languages do Kaggle users primarily use, and which languages would you recommend as a beginner language?

👉 Python vs R vs SQL?
👉 Jupyter? VS Code? PyCharm? Which editor should you use?
👉 Will the gender ratio of Kagglers change by age group?
👉 Also, are there differences in language use and occupation depending on gender?

Learn about Kagglers' interests and demographics through simple frequency analysis.

What if you have to do the same task over and over again? Create a function to reduce the amount of repetitive work.
I'll create a function that automatically analyzes the frequency by simply passing in the question number!

Try practicing by simply logging into Kaggle without any separate installation or download!

⚠️ Things to note before taking the class

  • We will not teach the basics of Python or Pandas, but will proceed directly to analysis.
  • We will not go into detail about how to use Python, Pandas, or visualization.
  • We only cover a few skills for survey analysis.
  • If you have no experience with Python, Pandas, or visualization, you may have difficulty taking the course.
  • We'll cover only the skills of how to directly check the responses to 39 questions with code and analyze them in a simple way.
