About This Chapter
Ethical Considerations in Scientific Investigations - Chapter Summary
In this chapter, you will have the opportunity to study ethical guidelines and expectations that should be followed and met during scientific experiments. You will go over such topics as risk management, bias, validity, safety and animal treatment in relation to scientific investigations. Once you have completed your study of these lessons, you should be able to:
- Identify reasons why experiment results might be inconsistent
- Name threats to experiment validity
- Relate ways to avoid bias when conducting a scientific experiment
- Understand safety risks associated with scientific experiments and how to avoid them
- Discuss the ethical treatment of animals used in experiments
Brief lessons contain definitions and detailed explanations to ensure that you fully understand each topic before moving from one lesson to the next.

Measure what you have learned or determine whether you need to continue your review of specific material by using self-assessment quizzes found in each lesson.
1. Identifying Potential Reasons for Inconsistent Experiment Results
Repeating an experiment helps ensure that you designed and implemented it correctly. But what if you don't get the same results each time? In this lesson, we'll explore potential reasons for this and how you might avoid it in the future.
2. Threats to External Validity: Sample Characteristics, Stimulus Characteristics & Experimental Arrangements
The goal of research is to generalize the results, but there are several things that can get in the way. This lesson examines three threats to external validity: sample characteristics, stimulus characteristics, and multiple-treatment interference.
3. How to Avoid Bias in Scientific Investigations
In this lesson, you will learn what it takes to conduct a proper scientific investigation while doing your best to avoid any possibility of bias. Learn where possible sources of bias can come from and what you can do about it.
4. Understanding Risks & Taking Safety Precautions in Science Experiments
An important step in designing your experiment involves identifying and evaluating any potential safety risks. Knowing what these risks are ahead of time can help you avoid accidents and dangerous situations, which helps keep the experiment safe and fun for all.
5. Ethics in Biomedical Research with Animals
Over the course of this lesson, you'll briefly learn about the history of animal use in research, some arguments for and against it, as well as how such research is regulated.
