Data Science Study Plan

🌟 Beginner Data Science Guide (6 Weeks) 🌟

🧠 Core Concepts (Explained Simply)

  • Data Cleaning: Fixing typos, missing values. Like wiping dust off a mirror.
  • Statistical Analysis: Finding patterns & averages. Like discovering trends in your shopping list.
  • Data Visualization: Turning data into charts. Like painting your data to tell a story.
  • Machine Learning (Bonus): Teaching machines to predict. Like training a pet to recognize your voice.

πŸ› ️ Tools You’ll Use

  • Python: The main language for data science.
  • Pandas: For working with CSV files and tables.
  • Jupyter: Combine code + output in notebooks.
  • Tableau Public: Create dashboards without coding.
  • Seaborn & Matplotlib: Beautiful visualizations.
  • Kaggle: Datasets + practice competitions.

πŸ“† 6-Week Study Plan (With Free Resources)

Week Focus Free Resource
1 Python Basics DataCamp Intro
2 Data Cleaning Kaggle Pandas Course
3 Exploratory Data Analysis Kaggle Challenge
4 Visualization Seaborn Tutorial + Tableau
5 Project Work Start dashboard project
6 Final Project Polish, publish & share your work!

πŸš€ Capstone Project: Interactive Dashboard

  • Dataset: Find one on Kaggle (e.g. Netflix, COVID, Sales)
  • Clean it: Use Pandas to fix missing values & typos
  • Analyze: Use charts (bar, line, pie) with Matplotlib/Seaborn
  • Build dashboard: Use Tableau or Streamlit/Plotly
  • Share: Post to Tableau Public or GitHub

πŸ§ͺ 5 Practice Problems (with Hints)

  1. Load Netflix CSV Dataset
    df = pd.read_csv('netflix_titles.csv')
  2. Count missing values
    df.isnull().sum()
  3. Filter for Movies Only
    df[df['type'] == 'Movie']
  4. Top 5 countries
    df['country'].value_counts().head(5)
  5. Plot movies per year
    df['release_year'].value_counts().sort_index().plot(kind='bar')

✨ Tip: Start with one line of code, and experiment with it!
