Question 19/30
Your friend suggests you should randomize the order of your data before splitting into a training and test dataset. Is your
friend right?
O No, your friend is not right. There is no benefit to doing
this, and the detail just makes the process too complex
No, your friend is not right. You should make sure your
work is always repeatable, and there is no way to get
repeatability if you randomly reorder the dataset.
Yes, your friend is right. It is possible your data was
originally organized in such a way that splitting will
give the model a biased view of the dataset (imagine
for example if all the data was ordered by some
feature).
