About This Chapter
FTCE: Data Analysis & Visualization - Chapter Summary
Watch fun and engaging video lessons in this self-paced chapter to improve your understanding of data analysis and visualization. As you study for an FTCE exam covering these topics, we can help you get reacquainted with circle graphs, a line plot in math, ways to calculate the standard deviation and more. After completing this chapter, you will be able to:
- Describe the process of creating and interpreting histograms
- Read and interpret bar graphs
- Define and share examples of circle graphs
- Share the definition of pictographs
- Provide examples of line plots in math
- Calculate the mean, median mode, range and standard deviation
Every lesson in this chapter is available in two formats: entertaining video lessons and full transcripts. The videos are fun to watch and average about 8 minutes each, and the transcripts are easy to read online or print to review at a later time. Paired with each lesson in this chapter is a multiple-choice quiz you can take anytime to check your knowledge of main concepts. Our practice exam enables you to test and confirm your comprehension of the entire chapter.
1. Creating & Interpreting Histograms: Process & Examples
Creating histograms can help you easily identify and interpret data. This lesson will give you several examples to better understand histograms and how to create them.
2. Reading & Interpreting Bar Graphs
In this lesson, you will learn about the parts of a bar graph and what they mean. You will look at the title, labels, and bars of data, and then you can practice reading and interpreting a sample bar graph.
3. Circle Graph: Definition & Examples
A circle graph is a circular chart divided into sections that each represent a percentage of the total. This lesson will define a circle graph and give some examples of types of circle graphs.
4. Pictograph: Definition, Examples & Images
Used widely in the present day to communicate rules and warnings on the road and elsewhere, pictographs were humankind's earliest form of written language. Look at some examples of pictographs, and then test your knowledge with a quiz.
5. What is a Line Plot in Math? - Definition & Examples
In this lesson, we will explore the functions and examples of a line plot. Also in this lesson, we will learn to create a line plot, create questions, and interpret data from a line plot.
6. 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.
7. Calculating the Mean, Median, Mode & Range: Practice Problems
Calculating the mean, median, mode, and range of a data set is a fundamental part of learning statistics. Use this video to practice your skills and then test your knowledge with a short quiz.
8. 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.
