You suspect that the spiciness of food served in a restaurant is positively correlated with number of soft drinks ordered. You have gathered several observations of people ordering food of different spice-levels and the number of soft drinks they ordered. What would be your next steps to test your hypothesis?

Question

Looks like you can eliminate the options that require you to have already plotted the data.
Which options remain?

henrietepurina · Answer

remove A because we have no data

henrietepurina · Answer

remove D its irrevevant

henrietepurina · Answer

remove C theres no point in doing it

henrietepurina · Answer

Im left with B is B the answer?

kropot72 · Answer

Well you do have the data, the reason being that the question states:
"You have gathered several observations of people ordering food of different spice-levels and the number of soft drinks they ordered."
Therefore you have not found a reason for removing A.
C and D can be removed, the reason being they cannot be performed unless the data has been plotted.

So we are left with a choice of A or B. Can you come to a conclusion easily without plotting the data?

henrietepurina · Answer

Oh yeah... sorry i didnt notice that its A because you have data thats not listed

kropot72 · Answer

You are correct, A is the correct choice.
