Can household_size be equal to 0?
It is one of the many Data cleaning task you have to complete. Another example, Married/Living together (marital status field), should not be less than 2 for household_size to make sense.
Perhaps because of the collection method i.e. via survey, we can't rely 100% on its integrity. Hence, the need to clean the data.
Thank you DrFad for adding value. You are correct regarding the martial status field, however, there is an error regarding the household size. We have updated the test and train files.
You will need to download the new test and train files, named Test_v2.csv and Train_v2.csv.
Awesome! Thank you Zindi for the prompt response.
