# Ch 52: ORELA Middle Grades Math: Data Collection

### About This Chapter

## ORELA Middle Grades Math: Data Collection - Chapter Summary

Brush up on your knowledge of different types of survey research and data collection methods through this group of short video lessons. The videos cover the following concepts in order to help you prepare for these types of questions on the ORELA Middle Grades Math exam:

- Types of survey research
- Observational and field research
- True experiments
- Experiments and observational studies
- Confounding variable and bias

Each lesson includes a 5-10 minute entertaining video, lesson transcript and multiple-choice quiz. The quizzes allow you to test your comprehension of mathematical data collection, and the videos have embedded tags so you can easily review areas that may need more exploration.

### ORELA Middle Grades Math: Data Collection Chapter Objectives

The ORELA Middle Grades Math test assesses your knowledge of basic math concepts and your teaching abilities to determine your readiness for teaching math to middle school students. The 150-question test includes topics from four main domains; the topics in this chapter may be encountered within the statistics, probability and discrete mathematics domain area. This domain makes up about 25% of the test questions.

All of the questions are multiple choice, and the questions relating to the topics in the Data Collection chapter may ask you to analyze the effects of bias and sampling methods and techniques. You can use the self-assessment quizzes and end-of-chapter exam to not only test your understanding of the information but practice solving problems similar to those you could find on the actual 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. True Experiment: Definition & Examples

A true experiment is thought to be the most accurate experimental research design. Learn more about true experiments from examples and test your knowledge with a quiz.

### 4. 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.

### 5. 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.

### 6. Confounding Variables in Statistics: Definition & Examples

Statistics can be a powerful tool in helping researchers understand and solve problems. However, there are faults that can occur in statistical research. In this lesson, you will learn about one of these faults: confounding variables.

### 7. 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 potential biases in research.

### 8. 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.
