Vector.push_back is returning same values even though rand() is used

I am new to programming, my vectors dataX and dataY for phase 2 of the program are returning the same values every time. I do not know why. Please help. I have spent several hours trying to figure it out, is the error in the calculations, or something to do with rand()? Please help.
