- Methods of survey research
- Observational and field research
- True experiment
- How experiments and observational studies differ
- Confounding and bias
- Sources of bias in polls and surveys

These lessons are packed with examples and are presented by professionals who know what's necessary for success on the exam. The lessons are enjoyable and informative, and you can study any time that's convenient on a computer or mobile device.

### Objectives of the OAE Middle Grades Math: Data Collection Chapter

Ohio teachers seeking certification to teach math at the middle grades level must pass the OAE Middle Grades Math exam. This exam is segmented into four domain areas, and questions on data collection and analysis are in the domain on statistics, probability and discrete mathematics, which accounts for 25% of the total test.

The exam is computer delivered and consists entirely of multiple-choice questions, similar to the brief quizzes that complement each of our video lessons. In addition to allowing you to assess your knowledge and see where you might need extra study, these quizzes offer practice in answering questions in a format similar to what you'll face on this OAE exam.

### 1. What Is Survey Research? - Definition, Methods & Types

This lesson explores the ways a researcher may employ the types of surveys used in research. We will also go over the strengths and weaknesses of each type of survey.

### 2. How Observational & Field Research Are Used to Collect Data

Psychologists have many different options for where and how to do research. Watch this video to learn more about the difference in field and lab research and the advantages and disadvantages of observational research

### 3. Experiments vs Observational Studies: Definition, Differences & Examples

There are different ways to collect data for research. In this lesson, you will learn about collecting data through observational studies and experiments and the differences between each.

### 4. Confounding & Bias in Statistics: Definition & Examples

Statistics can be a powerful tool in research. Unfortunately, statistics can also have faults. In this lesson, you will learn about the faults in statistics and how to critically examine research.

### 5. Bias in Polls & Surveys: Definition, Common Sources & Examples

When Mark Twain commented that there were three types of lies, he included statistics in the count. In this lesson, we look at bias, one of the ways in which statistics can mislead, and in some cases, flat out lie to us.
