Hey, Alex! Great choice to start working with ML.
TV, Radio, Newspaper : Budget in thousands of dollars of advertising a product using these mediums. (Ad on TV, Ad on Radio, Ad on Newspaper)
Sales: Amount of Sale in thousands of units with the above budget. (Total sale)
Ignore the thousands of. Just make sure you understand what it represents.
So, what we are trying to find out is if there is any relation between TV’s budget and net Sale.
It might be that the Ads on Radio do not really affect the Sales, or maybe the Sale is immensely affected by Newspaper.
That’s what our model predicts.
