Identifying Sources of Unavoidable Experimental Error

1. Identifying Sources of Unavoidable Experimental Error

Good data are essential for any experiment. But no matter how hard you try, error in your data is unavoidable. In this lesson, you'll learn about the types of unavoidable experimental error to be on the lookout for and how to reduce their occurrence in your data.

Identifying Potential Reasons for Inconsistent Experiment Results

2. 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.

Evaluating Data: Precision, Accuracy & Error

3. Evaluating Data: Precision, Accuracy & Error

The data you present as a scientist need to be as accurate, precise and error-free as possible. In this lesson, we'll discuss what each of these terms means, as well as how error is introduced into measurements and other data collection.

Using Appropriate Tools for Scientific Tests & Data Collection

4. Using Appropriate Tools for Scientific Tests & Data Collection

A properly run experiment depends on using the right tools, both for data collection and analysis. In the end, it will save you time, money and frustration to spend some time planning out which tools are most appropriate for your work.

Understanding Statistical Variability

5. Understanding Statistical Variability

Summary statistics are great for providing an overview of your data, but sometimes you need to know more, like distribution. Understanding this variability will give you a clearer picture of all your data and how they relate to each other.

Importance of Controlled Tests in Scientific Research

6. Importance of Controlled Tests in Scientific Research

One way to ensure that your experimental results are meaningful and relevant is to control for factors that may affect your experiment. In this lesson, we'll talk about how to do this and why it's so important in scientific research.

Understanding Risks & Taking Safety Precautions in Science Experiments

7. 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.

Print & Electronic Sources for Scientific Research

8. Print & Electronic Sources for Scientific Research

Sources provide you with helpful background information that support your own work. You can find sources both online and in printed materials. There are benefits and drawbacks to each, so you'll need to consider which is best for you and your project.

Scientific Sources: Accuracy, Reliability & Validity

9. Scientific Sources: Accuracy, Reliability & Validity

It's important to use other sources to support your work, but what's even more important is to use the right ones. Sources should be valid, reliable, and accurate, but it's not always easy to tell which ones meet these criteria.

Solve for Unknowns in Scientific Equations

10. Solve for Unknowns in Scientific Equations

Calculating a missing value in an equation is something you may come across in your scientific analyses. As long as you know the relationship between the variables in the equation, as well as the rest of the measured values, this is a relatively straightforward process for you to master.
