Dependent and Independent Variables Instructions: For each of the following research designs‚ identify the dependent and independent variables. 1. To investigate the effects of exercise on mathematical problem-solving ability‚ a researcher assigned subjects to one of two groups. One group did 50 jumping jacks and the other group did 200. After exercising‚ both groups did a set of math problems. 2. A researcher hypothesized that talking to plants enhances their growth. To test her hypothesis‚ she gave

through by measuring the changes in the selected variables. The Variables that we selected were stem length‚ root length‚ the amount of leaves that grew on a plant and the overall size of the plant measured in height. For this experiment‚ we had three test groups‚ the first two groups had five seeds and the third group has 10 seeds. The reason for that is because we introduce the third group to interspecific competition. We wanted to find out if variables such as competition will have an effect on

Hypothesis When I apply four different seasonings (cinnamon‚ oregano‚ cumin‚ salt) to four cuts of the same brand of bologna‚ salt is going to have the strongest inhibitory effect and the bologna will not spoil. Variables Dependent Variable- The dependent variable of my experiment is the bologna meat. Independent Variable- The independent variable of my experiment is the amount of seasoning that I will be applying to my dependent variable. Constant Variable- The constant variable of my
