Before you train any model, you need to understand your data.
Skip this step and you'll spend hours debugging the wrong thing.
In this episode of ML & AI From Scratch, we walk through a complete
Exploratory Data Analysis (EDA) workflow using pandas and matplotlib
on the California Housing dataset.
By the end of this video you'll know how to:
✅ Inspect any DataFrame in 5 commands (.shape, .info, .describe...)
✅ Find and fix missing values — with the right strategy each time
✅ Visualise distributions with histograms and boxplots
✅ Build a correlation heatmap to find the most useful features
✅ Use scatter plots to spot linear relationships before modelling
✅ Avoid 4 common data pitfalls that trip up even experienced devs

💻 EDA STARTER CODE (run this on any dataset):
import pandas as pd
import matplotlib.pyplot as plt
import seaborn as sns
df.shape
df.info()
df.describe()
df.isnull().sum()
sns.heatmap(df.corr(), annot=True, cmap='coolwarm')
plt.show()
