Data Analysis

Getting started with data analysis with Kaggle surveys

What is Kaggle? Every year, Kaggle conducts a survey of users around the world. When you want to learn data science, you may have many questions. Is it too late to start? Which language should I choose between Python and R? How much is the salary? Find out by reading the responses from users around the world! With just a few powerful features of Pandas, you can perform frequency analysis and data visualization.

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.

          Your voice is calm, and you deliver the lectures in a way that's easy to listen to. Explaining each line of code in detail made it easy to understand.
