Remember that a hypothesis does not need to state the correct relationship (as in the memo) between the dependent and independent variables to earn the mark(s). An answer such as the following may earn the two marks: "The conductivity of the silver nitrate solution decreases with an increase in the concentration of the silver nitrate solution at a constant temperature." The two marks may be awarded because of:
- The correct dependent and independent variables are given.
- The correct controlled variable is given.
- A relationship (not necessarily correct) is given.
