BIO 181 Lab Midterm Grand Canyon UniversityWhat is a hypothesis? - correct answer - A tentative explanation thetas given and can be tested. - Predictions that can be tested by conducting observations or by performing experiments. What is a null hypothesis? - correct answer - Is a default assumption that an explanation or prediction is false. What is an alternative hypothesis? - correct answer - Is the alternative explanation to the null hypothesis thetas accepted as a best explanation if the null hypothesis is rejected. What is a dependent variable? - correct answer - The elements measured or counted by an investigator in response to a change in an experiment as a result of a change in the independent variable. What is an independent variable? - correct answer - The variable that drives/manipulates a change in the dependent variable. the investigator assumes that experimental outcomes can be predicted and even changed by changing/manipulating an independent variable. What is an experimental group? - correct answer - The section of the experiment involving manipulation of an independent variable. What is the control group? - correct answer - The section of the experiment in which an independent variable is omitted or set a standard value. The control group helps to evaluate how the manipulation of the independent variable affects the outcome of the experiment. Why is it important to formulate a hypothesis? - correct answer - It involves suggesting possible answers to proposed scientific questions in a predictive and explanatory form.
