Reseаrchers hypоthesize thаt chоndrоitin reduces joint pаin and increases agility in senior dogs. They design an experiment to test their hypothesis where they give 100 senior dogs a 500 mg chondroitin supplement a day and another group of 100 senior dogs a placebo without chondroitin. Every day for a month, all dogs will be measured and timed on a simple agility run. Results will then be compared between groups to determine how effective the treatment was. In this experiment: what was the dependent variable? [blank1] what was the independent variable? [blank2]
