THEA Test: Calculating & Plotting Data Objectives
The THEA Test: Calculating & Plotting Data chapter helps you prepare for questions found in the mathematics section of the test. This section consists of 50 multiple-choice questions that explore fundamental math, problem solving, algebra and geometry. You can prepare for questions by reviewing the lessons in their video or transcript formats. Lesson quizzes and a chapter exam can assess your readiness to answer questions on the exam.
The test is designed to ensure that students in Texas are prepared to enter state public colleges and universities as freshmen. It consists of a math, writing and reading section, all of which are scored separately. Passing the math section of the test requires earning a minimum score of 230.
1. What Are the Different Parts of a Graph?
Being able to read a graph isn't just vital for an algebra class. Graphs and charts are used everywhere! We'll take a crash course on the basic x/y plane used in algebra and the fundamental vocab you need.
2. What is a Pie Chart? - Definition & Examples
Learn how useful pie charts can be in your life and how you can gain information by just glancing at one. Look over some examples, learn how to create pie charts yourself, and then take a short quiz.
3. Understanding Bar Graphs and Pie Charts
In this lesson, we will examine two of the most widely used types of graphs: bar graphs and pie charts. These two graphs can provide the reader with a comparison of the different data that is displayed.
4. What is a Line Graph? - Definition & Examples
In this lesson, we'll explore the function and examples of a line graph. Then, you will learn to create questions and interpret data from line graphs. A brief quiz follows.
5. How to Construct Graphs from Data
This video describes how to create a line graph and explains the four main parts that graphs need to contain: 1. previously collected data, 2. picture representations, 3. use of the correct graph type, and 4. labels. This lesson also covers dependent and independent variables.
6. Reading and Interpreting Line Graphs
Watch this video lesson to find out how useful line graphs can be and how much information you can gain just from looking at one. Learn how you can apply that information in your own life to help you make better decisions.
7. 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.
8. Scatterplots and Line Graphs: Definitions and Uses
After watching this video, you will be able to understand scatter plots and line graphs. You will also be able to use them to tell people a story about what you see and observe. You will also be able to read them.
9. What Is the Median? - Definition & Explanation
The median is a statistical term that is one way of finding the 'average' of a set of data points. This lesson will show you how to determine the median, differentiate it from the other ways of finding the average, and give some real life examples.
10. Mean: Definition & Sample Problems
The arithmetic mean of a group of numbers is the technical term for the average of a group of numbers. This lesson will tell you how to compute the mean, give some examples and provide a quiz at the end so you can practice.
11. The Mean vs the Median: Differences & Uses
Most people can find the mean and the median of a data set, but do you know when to use the mean and when to use the median to describe the information?
12. 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.
13. 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.
