About This Chapter
Collecting Scientific Data - Chapter Summary
How do you maintain scientific data integrity? Which analytical tools are best used for scientific tests and data collection? What is qualitative research? Explore the answers to these questions and more when you review the lessons in this short chapter. Each lesson contains definitions and examples to help you fully understand the material being discussed. Once your review of chapter is complete, you should be able to:
- Identify appropriate tools used for collecting and testing scientific data
- Describe techniques you can use to ensure the integrity of scientific data
- Define qualitative research and list sources for it
- Discuss quantitative data and its usefulness
- Determine sample size for any given scientific data collection project
Lessons present each topic with easy-to-follow language and examples are accessible at any time, from any device. Watch the videos as many times as needed or print lesson transcripts to create handy reference tools. Determine how much you have retained or your need to continue your review by taking self-assessment quizzes for each lesson.
1. 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.
2. Techniques to Maintain Data Integrity from Scientific Instruments
In order to be a good scientist, you have to make sure that your data is worthwhile. But how can you be sure of that? This lesson goes over many of the techniques you can use to be sure that your data is both accurate and precise.
3. What is Qualitative Research? - Definition, Sources & Examples
Sometimes research does not involve simple numbers that you can analyze. When that happens, where do researchers get their data? In this lesson, we'll look at qualitative data and the major sources of it.
4. What is Quantitative Data? - Definition & Examples
Watch this video lesson to find out the difference between saying you have seven apples and saying that those apples are delicious. You will learn about quantitative data and why it is useful.
5. How to Determine Sample Size
How many subjects should a researcher use in his or her experiment? In this lesson, we'll examine the elements that go into sample size, including how to figure out how big a sample should be and what real-world issues influence sample size.
