1. what is the significance of data in scientific research?

a) it is used to support or refute a hypothesis
b) it is irrelevant to the research process
c) it is only important for qualitative studies
d) it is a form of opinion

Explanation:

• Question 4: Environmental ethics focuses on the moral relationship between humans and the environment. Option A is about psychology (human behavior study). Option C is about economics (economic impact). Option D is about technology (technological advancements).
• Question 5: A controlled study isolates the effect of the independent variable on the dependent variable. Option A is incorrect as not all variables can be eliminated. Option B is wrong as it's about one independent variable. Option D is not the main design purpose.
• Question 6: A prediction in scientific research is a statement about what will happen based on a hypothesis. Option A is just a guess. Option C is a summary. Option D is an explanation of a theory.
• Question 7: A dependent variable is the variable that is measured to assess the effect of the independent variable. Option A is the independent variable. Option C is a constant. Option D is irrelevant.
• Question 8: Data in scientific research is used to support or refute a hypothesis. Option B is incorrect. Option C is wrong as data is important for all studies. Option D is not a form of opinion.
