1.Automotive Dataset Cleaning and Analysis
Data Education · 2026
A data educator created this dashboard to document the process of fixing structurally defective raw records within the Auto MPG dataset. The interface details specific corrections, such as stripping terminal periods from weight values and applying data mapping to convert numeric origin codes into readable regional labels like Japan and Europe. After resolving missing horsepower records, the resulting analysis shows average fuel efficiency improving from 17.7 MPG in 1970 to 31.7 MPG in 1982, while large engines dropped from 62.1 percent of the sample to just 3.2 percent.
What it shows:
Replacing defective characters and standardizing labels ensures accurate historical trend calculations.
