Why is the answer "No" for the first question
Can you elaborate why is the answer No for the first question? cannot we conduct a regression analysis if there is a relationship between cones orders and sales of ice-cream?
imo there is no any form of propably causality. Beside trivial case (order 0 cones, sell 0 icecreams etc)
Hi - I think causality is the key here. There is a relationship between the two events, however the one event occurring does not necessarily cause the other event to occur. For instance, ordering a certain number of cones will not cause a certain number of ice creams to be sold. In other words, the ordering of a certain number of cones does not mean that a certain number of ice creams will be sold as other factors (daytime temperature, shop location, flavors of ice cream) cause ice cream to be sold.
