Amanda had trouble finishing her homework. She’d sit at her desk in her bedroom and stare at her book, but her mind would wander and she couldn’t finish her work. She wondered if she would finish if she turned off all of the distractions around her. She got her homework together and turned off the TV and all of the other things in her room that made noise- making her room silent. She predicted that eliminating “background noise” would help her finish more homework problems.
What is the Independent Variable?
the tv show on the tv
the background noise
how much homework was completed
her desk
