# Ch 55: CEOE Advanced Math: Statistics

### About This Chapter

## CEOE Advanced Math: Statistics - Chapter Summary

The lessons in this chapter take a look at several core terms and components of statistical study, with video lessons providing an efficient and effective review of:

- Calculating mean, median, and mode
- Measures of dispersion and skewness
- Quantitative data
- Continuous, discrete, and categorical variables
- Scales of measurement
- Calculating the standard deviation
- Regression analysis

Each lesson within the chapter allows you the opportunity to check your understanding with a practice quiz, after which your progress is recorded so you can see how far you've come. Taught by professional instructors who are available for questions, each lesson includes both a video as well as a transcript so you can choose the way you learn.

### CEOE Advanced Math: Statistics Chapter Objectives

The CEOE Advanced Mathematics exam is an aspect of the teacher certification process in Oklahoma for those who want to teach advanced math classes. The exam includes 80 multiple-choice questions, spread across five subareas, and one constructed-response (written) assignment that will pertain to the relations, functions, and algebra subarea.

The topics covered in this chapter will help you prepare for the probability, statistics, and discrete mathematics section of the exam, solidifying your knowledge of the ins and outs of these subjects. This subarea makes up 14% of the exam's total content.

### 1. 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.

### 2. How to Calculate Mean, Median, Mode & Range

Measures of central tendency can provide valuable information about a set of data. In this lesson, explore how to calculate the mean, median, mode and range of any given data set.

### 3. Measures of Dispersion and Skewness

Watch this video lesson to learn how you can describe your data using two different statistical characteristics. Learn what it means for your graph to have variability and what it means for your graph to be skewed.

### 4. What is Quantitative Data? - Definition & Examples

Watch this video lesson to find out the difference between saying you have seven apples and saying that those apples are delicious. You will learn about quantitative data and why it is useful.

### 5. Continuous, Discrete & Categorical Variables: Definition and Examples

When doing research, variables come in many types. In this lesson, we'll explore the three most common types of variables: continuous, discrete, and categorical.

### 6. Scales of Measurement: Nominal, Ordinal, Interval & Ratio

When doing research, variables are described on four major scales. In this lesson, we'll look at the major scales of measurement, including nominal, ordinal, interval, and ratio scales.

### 7. 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.

### 8. Regression Analysis: Definition & Examples

Watch this video lesson to learn about regression analysis and how you can use it to help you analyze and better understand data that you receive from surveys or observations. Learn what is involved in regression analysis and what to look out for.
