Week 2 Assignment : Data Source

[Sunil Mammen]

Hi,

I think I am at a roadblock from the getgo. I downloaded the data from the link and was trying to compare it with the attribute description. Column 2 is meant to be Diagnosis ( B or M) but the data link has a bunch of numbers. I checked on Kaggle for a similar description and their data had B and M as the actual values. Just wondering if I was using the data from the UCI link wrong or should I go with the Kaggle version of the data:

https://www.kaggle.com/uciml/breast-cancer-wisconsin-data

Hope someone could shed some light 🙂 Thanks very much !

The dataset I believe has been processed from its original. The data with a bunch of numbers with no B or M diagnosis is in fact described here. http://archive.ics.uci.edu/ml/machine-learning-databases/breast-cancer-wisconsin/breast-cancer-wisconsin.names

An excerpt from the above file is below:
