# Ch 51: NES Middle Grades Math: Data Collection

### About This Chapter

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

In this chapter, you will get ready for the National Evaluation Series (NES) Middle Grades Mathematics exam by reviewing some basic practices for collecting data before evaluating it statistically. The lessons are focused on the material you are likely to be tested on during the exam, delivered in bite-sized chunks to help you fit your studies into your schedule. The content of these videos discusses:

- Methods and types of survey research
- Observational and field research
- Observational studies and experiments
- Confounding variables
- Bias in statistics, surveys, and polls

Each lesson is centered on a fun and interesting video that contains expert instruction on, and real-world applications of, each data collection concept. The lesson is then reinforced with a brief quiz, a worksheet with links back to related content in the videos, and a chapter test to make sure everything sank in. Be sure to return to trouble areas in the content using the navigation sidebar and video tags, which will get you right to the specific material you need to review.

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

The NES Middle Grades Math exam is entirely computer-based and multiple-choice. It has 150 questions, which you will have 4 hours and 15 minutes to complete. This material falls within the Statistics, Probability, and Discrete Mathematics content domain (25% of the test), particularly objective 0010. To pass the test, you must achieve the national benchmark score of 220.

Registration is generally completed through the NES website, though the state in which you are seeking licensure may have different registration requirements so check their website as well before registering. Score reports are delivered in about two weeks, but you can receive your scaled score immediately following the exam at the testing center.

### 1. 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

### 2. 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.

### 3. 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.

### 4. 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.

### 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.
