Question
- A. Use the method carefully, name the independent variable, dependent variable and a controlled variable, then evaluate validity, reliability, uncertainty and contamination risk before drawing a conclusion.
- B. Only describe the final observation; variables, controls and evaluation are not needed.
- C. Change several variables at once to make the result more visible.
- D. Assume the result is valid without considering contamination, uncertainty or reliability.
Answer
The correct answer is: Use the method carefully, name the independent variable, dependent variable and a controlled variable, then evaluate validity, reliability, uncertainty and contamination risk before drawing a conclusion.
Explanation
This is correct because A-Level Biology practical answers need method reasoning, variables, controls and evaluation. For required practical work, state the method, independent variable, dependent variable and one controlled variable. Keep controls constant, then evaluate validity, reliability, uncertainty, contamination risk and whether the evidence supports the genetic conclusion.
Common mistake
