Answer:
BY USING MORE NEUTRAL LANGUAGE TO AVOID LEADING QUESTION.
Step-by-step explanation:
Construct validity defines how well a test or experiment measures up to its claims.
Leading questions are questions which subtly prompts the respondent to answer in a particular way. Leading questions result in biased or false answers and so, they are undesirable.
In Jenny's case, she is against cutting down of the tree in the campus and so plans to find out if others feel the same way, she does this by asking the students a leading question just so that they can answer in her favor.
To improve the construct validity of the question, Jenny has to use MORE NEUTRAL LANGUAGE TO AVOID LEADING QUESTION.
Neutral languages or questions do not carry any hidden-agenda. They are open-minded and allow people to think deeply about the answer.
Therefore, the question could be changed to improve its construct validity by USING MORE NEUTRAL LANGUAGE TO AVOID LEADING QUESTION.
