Answer and Explanation:
1. <u>Hypothesis</u>: <em>The more sunflower seeds the students get, the better they will do on a quiz.</em>
2. <u>Dependent Variable</u>: Responding variable refers to the dependant variable, which response depends on any change in the independent variable. A change in the dependent variable might be proportional or inversely proportional to the change in the manipulated variable. In the exposed example, the dependent variable is the response of each group to sunflowers seeds expressed as their grades on quizzes.
3. <u>Independent Variable</u>: <em>number of sunflower seeds. </em>Manipulated variable refers to all the variables in an experiment that provoke a response in another variable. They are also known as independent variables. The researcher can change these variables to see what changes it implies in an object, process, trait, or anything that depends on them. In the exposed example, the researcher manipulates the number of sunflower seeds promised to each group.
4. <u>Constant Control Group</u>: Group 1, which does not receive any sunflower seeds. The election of a control group is essential in an experiment. Its principal purpose is to allow the discrimination of the results obtained by the treatment in the study, in this case, the provision of sunflower seeds, from the results that might be a consequence of other factors. The control group must be selected from the same population of the treatment group. All groups must be similar in every variable that might influence the results, except for the study treatment
5. <u>Experimental Group</u>: Groups 2 and 3, that received different amounts of seeds.
The answer is (d) evaporates.
