Assalam-o-Alaikum! Welcome back to Class 4 of the Future Minds Bootcamp 2026!

Data par koi formula ya AI model lagane se pehle usay properly "samajhna" sab se zaroori step hai. Aaj ki is live class mein hum data analytics ke core concepts ki gehrai mein jayenge. Agar aap ek behtareen Data Analyst banna chahte hain, toh yeh class aapke analytical mindset ko mukammal taur par transform kar degi!

What we covered in Class 4 in detail:

1. Understanding of Data (Data ko Samajhna)
Data sirf numbers aur text ka majmooa nahi hota; iske peeche ek story hoti hai.

Context: Yeh data kahan se aaya aur kyun collect hua?

Rows & Columns: Observations (records) aur Features (variables) ka concept.

Data Quality: Missing values aur impossible entries ko pehchanna.

2. Dimensions of Data (Data ki Dimensions)
Data analytics aur Business Intelligence (BI) mein dimensions ko do tarah se dekha jata hai:

Shape of Data: Dataset ka size (Rows x Columns).

Dimensions vs. Measures: Categorical data (jinhe aap filter/group karte hain jaise City, Date) aur Quantitative data (jin par math apply hota hai jaise Total Sales, Profit) ke darmiyan farq.

3. Composition of Data (Parts-to-Whole)
Data Composition ka seedha sa matlab hai ek mukammal cheez kin chotay hisson se mil kar bani hai.

The Core Concept: Total revenue mein se kis category ka kitna hissa hai?

Metrics & Visuals: Composition ko Percentages (%) mein measure karna aur usay Pie Charts, Donut Charts, ya 100% Stacked Bar Charts ke zariye visualize karna.
