About This Chapter
OAE - Biology: Analysis & Interpretation of Data - Chapter Summary
These video lessons cover how to use data in order to form analysis and draw logical conclusions. We provide a review of concepts like standard deviation and internal validity, so you'll be capable of interpreting scientific data on the OAE Biology exam. After completing this chapter, you'll be able to:
- Work with significant figures and scientific notation
- Convert between the metric system and other common units of measurement
- Use descriptive statistics
- Interpret basic errors in data
- Differentiate between mean, median and mode and find each in a data set
- Determine standard deviations
- Find trends and examine relationships using data
- Make estimates and hypotheses using categorical and quantitative data
- Draw conclusions based on internal validity
All of our video tutorials were put together by innovative instructors to help you review complicated subjects like data analysis in the easiest possible way. Once you think you know your way around categorical and quantitative data, try out our self-assessment quizzes to get a feel for the types of questions you'll encounter on the OAE Biology exam.
OAE - Biology: Analysis & Interpretation of Data - Chapter Objectives
Passing the Ohio Assessments for Educators (OAE) Biology exam is a requirement for aspiring life sciences teachers Ohio. In order to achieve a passing grade, test-takers must earn a score of 220.
The OAE Biology exam consists of five domains, including one focused on the nature of science. This section includes questions related to data analysis and interpretation that this chapter is designed to help you with. Twenty percent of the questions on the exam are in this domain. You will need to complete the full exam in three hours. The computer-based test is made up of 150 multiple-choice questions.
1. Significant Figures and Scientific Notation
Are 7.5 grams and 7.50 grams the same? How do scientists represent very large and very small quantities? Find out the answers to these questions in this video.
2. Common Unit Conversions
Watch this video lesson, and you will become a pro at converting between inches and feet, between feet and yards, and between quarts and gallons. Learn the special numbers involved in each conversion.
3. The Metric System: Units and Conversion
Just like you and your friend communicate using the same language, scientists all over the world need to use the same language when reporting the measurements they make. This language is called the metric system. In this lesson we will cover the metric units for length, mass, volume, density and temperature, and also discuss how to convert among them.
4. What Are Descriptive Statistics? - Definition and Uses
This lesson is a simple walk-through of the common types of descriptive statistics and why they are important for understanding psychological research. You will likely be familiar with many of them but some you may not be.
5. Mean, Median & Mode: Measures of Central Tendency
By describing the data using central tendency, a researcher and reader can understand what the typical score looks like. In this lesson, we will explore in more detail these measures of central tendency and how they relate to samples and populations.
6. Calculating the Standard Deviation
In this lesson, we will examine the meaning and process of calculating the standard deviation of a data set. Standard deviation can help to determine if the data set is a normal distribution.
7. Statistical Analysis: Using Data to Find Trends and Examine Relationships
Many different organizations use statistical analysis to describe and analyze data and to predict future trends. Learn about the different types of statistics in this video lesson.
8. The Relationship Between Variables: Correlation Coefficient & Scatterplots
The focus of this lesson is on how both correlation coefficients and scatterplots convey the same message. Specifically, this lesson will explore how these two can reveal the same information but in different ways.
9. Make Estimates and Predictions from Categorical Data
Categorical data can be estimated but not predicted. Learn why in this video lesson along with how to read and gather information from a bar graph of categorical data.
10. Making Estimates and Predictions using Quantitative Data
Watch this video lesson to learn how you can read a scatter plot to learn more about a particular situation. Also learn how you can make estimates within the range of data you have and predict what may happen outside the range of data.
11. Drawing Conclusions Based on Internal Validity
When a researcher gets the results of their study back, how do they know that the independent variable caused the results? In this lesson, we'll look at how internal validity shapes the way researchers draw conclusions about their research.
