The Scientific Method: Steps, Terms & Examples

1. The Scientific Method: Steps, Terms & Examples

The scientific method is more than just hypotheses and experiments. In this lesson, we'll explore the themes and variations that make up the world of science.

Developing a Scientific Hypothesis

2. Developing a Scientific Hypothesis

This video describes how to create a hypothesis and includes the three main things needed to create a strong hypothesis. You'll learn how to make a clear statement that can be both tested and measured.

Designing an Experiment to Test a Given Hypothesis

3. Designing an Experiment to Test a Given Hypothesis

A well-written hypothesis is the key to any well-designed experiment. In this lesson, we'll work through the process of designing an experiment based on the hypothesis it's meant to test and see how the two work to complement each other.

What is Sampling in Research? - Definition, Methods & Importance

4. What is Sampling in Research? - Definition, Methods & Importance

The sample of a study can have a profound impact on the outcome of a study. In this lesson, we'll look at the procedure for drawing a sample and why it is so important to draw a sample that represents the population.

Using Appropriate Tools for Scientific Tests & Data Collection

5. 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.

Drawing Logical Conclusions from Experimental Data

6. Drawing Logical Conclusions from Experimental Data

Experimental results are what scientists like to share with each other, but it's important to understand what those data mean. We do this in the final step of the experimental process, when we draw meaningful conclusions from the results we obtained.
