Analysis

This page walks through the evidence step by step: first looking at whether academic factors separate placed from non-placed students, then testing whether internship experience changes that picture, and finally checking whether communication skills add anything further.

Step 1: Do CGPA and IQ Separate Placed Students?

Yes — placed students cluster clearly toward the upper-right, meaning high CGPA and high IQ together. The next question is how strong the CGPA relationship is on its own.

Step 2: How Strong Is the CGPA Relationship, Specifically?

Splitting students into five equal-sized CGPA groups makes the relationship concrete: placement rate climbs sharply and steadily from the lowest to the highest CGPA band. With CGPA established as a strong driver, the next question is whether internship experience changes this picture.

Step 3: Does Internship Experience Change the CGPA Story?

No — the two internship lines sit almost exactly on top of each other across the entire CGPA range. This is the first sign that internship experience isn’t doing meaningful work once CGPA is already known — a finding the Model page confirms with formal statistics.

Step 4: Does Communication Ability Add Anything Further?

Yes — placement rate climbs steadily across communication skill quintiles, similar in shape to the CGPA pattern in Step 2.

Conclusion

Four steps, four questions, and a consistent answer each time. Students with higher CGPA and IQ are more likely to be placed. Splitting students into groups by CGPA alone shows a clear, steady climb in placement rate from lowest to highest, the curve above makes that relationship concrete across the full range of CGPA. Internship experience, on the other hand, changes almost nothing — students with and without one follow virtually the same placement pattern once CGPA is already known. Communication skills tell the same story as CGPA: a steady, visible climb in placement rate from low to high.

Put simply: academic performance and communication ability are real, visible drivers of placement — internship experience is not. The Model page puts formal statistics behind this same conclusion.
