Ch 3: Analyzing & Evaluating Scientific Data

About This Chapter

In this chapter, you'll learn the different methods scientists use to interpret, analyze, and record data. Use these video lessons and their accompanying quizzes to refresh your understanding of the scientific method so you can feel more confident going into an upcoming exam.

Analyzing & Evaluating Scientific Data - Chapter Summary

This chapter reveals how to use scientific data to create graphs and how to read both scientific charts and graphs. You'll also learn several different methods scientists use to analyze statistics. These lessons detail scatterplots and correlation, as well as the relationship between the two.

Additional lessons discuss the importance of precision in scientific measurements, and the related concepts of reproducibility and accuracy. You'll also learn about the importance of the steps in the scientific method and how to present scientific findings in both written and oral form. Once you've completed this chapter, you'll understand how to:

  • Construct and interpret a scatterplot
  • Relate reproducibility to scientific experimentation
  • Take precise measurements when taking scientific data
  • Follow the order of steps in the scientific method
  • Present scientific data orally and in writing

How to Construct Graphs from Data & Interpret Them

1. How to Construct Graphs from Data & Interpret Them

After watching this video, you should be able to explain what a graph is, construct a scatter plot, and interpret scatter plots from scientific data. A short quiz will follow.

How to Read Scientific Graphs & Charts

2. How to Read Scientific Graphs & Charts

How do scientists summarize their findings with visual aids? In this lesson, explore the different types of tables, charts and graphs that scientists use. Learn to read these effectively as a preview to your science studies.

Statistical Analysis: Methods & Techniques

3. Statistical Analysis: Methods & Techniques

Statistical analysis is the process of collecting and reading data so that one can describe past behavior and characteristics and predict future ones. This lesson will give the definition and formulas of different methods you can use.

Scatterplot and Correlation: Definition, Example & Analysis

4. Scatterplot and Correlation: Definition, Example & Analysis

A scatterplot is used to graphically represent the relationship between two variables. Explore the relationship between scatterplots and correlations, the different types of correlations, how to interpret scatterplots, and more.

Measurements & Uncertainty in Science

5. Measurements & Uncertainty in Science

In this lesson, you will discover the importance of precision and accuracy in science while learning to make measurements. Also, you will understand how to perform calculations with measurements that conserve precision and limit uncertainty.

Evaluating Data from Scientific Investigation

6. Evaluating Data from Scientific Investigation

After watching this video, you will be able to explain the meaning of the terms 'accuracy' and 'reproducibility,' or precision, as they relate to science experiments. A short quiz will follow.

Connecting the Steps of the Scientific Method

7. Connecting the Steps of the Scientific Method

While the scientific method is divided into different steps, each of those steps is connected to the others. From making observations to drawing conclusions, the logical order and flow is what makes this process work so well in science.

Presenting the Scientific Process Orally or in Writing

8. Presenting the Scientific Process Orally or in Writing

Part of being a good scientist involves sharing your work with others. Two of the most common ways this is done is through written works and oral presentations, both of which require a certain amount of care and skill.
