Hypothesis,
Independent variable.
Dependent variable.
Possible extraneous variable.
Informal Experirment : Carolyn is frustrated that getting her third-grader son, Jacob, to complete his homework after school results in a daily argument. She wants to find a strategy that will reduce the struggle. She has always allowed him to watch TV or play for an hour before beginning his homework. She thinks that maybe having him complete the work before watching TV or playing will have better results. She decides to alternate the schedule for one month. During Weeks 1 and 3, she has Jacob complete his homework before playing and records the amount of time it takes him to get started on his homework. During Weeks 2 and 4, she switches to the former routine of allowing an hour of play time before beginning homework. She records the amount of time it takes him to get started on his homework. She compares the total times for the two approaches.
Explanation / Answer
Hypothesis: Watching TV or play before the beginning of the homework distracts the child and makes it difficult for him to focus on his studies and get started on his homework.
Independent variable: timing of the TV or play before the beginning of the homework or after the homework.
Dependent variable: the amount of time it takes to get the child started on his homework.
Possible extraneous variable: physical conditions of the room in which the child is doing the homework or the diet of the child prior to his sitting down for homework.
