Working with Data - Chapter Summary

Learn how to work with several varieties of data. You can prepare for the NY Regents Integrated Algebra test with these definitions, examples, practice problems and quizzes provided through user-friendly lessons. Instruction for all of the following topics is included:

  • Uses of categorical data
  • Discrete and continuous quantitative data
  • Using histograms
  • Center, shape and spread in a graph
  • Quantitative variable relationships
  • Line graphs, box plots and scatterplots
  • Bivariate data
  • Correlation coefficient

Each lesson offers a brief video presentation, a full transcript of the text and a short, multiple-choice quiz. Feel free to use the lessons as many times as you like. Video tags can quickly take you back to specific portions of the videos for additional review. Some lessons contain links to extra text-only lessons that provide even more information about essential terms and topics.

Integrated Algebra Regents Exam Objectives

New York State requires that high school students pass five subject-area tests, with scores of at least 65, in order to graduate. The Integrated Algebra exam will transition into the Algebra I test, when full changeover to the Common Core Learning Standards has taken place.

On this test, you'll have the chance to demonstrate an understanding of concepts related to number and quantity, statistics and probability, algebra and functions. Our quizzes can provide valuable practice for the multiple-choice portion of this three-hour test.

Statistical Analysis with Categorical Data

1. Statistical Analysis with Categorical Data

Learn why percentages are so important when analyzing categorical data in this video lesson. Watch as the data is turned into a data table and a visual bar graph as ways to analyze the data.

Summarizing Categorical Data using Tables

2. Summarizing Categorical Data using Tables

Watch this video lesson to find out why data tables are an excellent way to summarize your categorical data. Learn what you need to do to your data before constructing a table and the two ways you can show your data.

Make Estimates and Predictions from Categorical Data

3. Make Estimates and Predictions from Categorical Data

Categorical data can be estimated but not predicted. Learn why in this video lesson along with how to read and gather information from a bar graph of categorical data.

What is Quantitative Data? - Definition & Examples

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.

What is a Histogram in Math? - Definition & Examples

5. What is a Histogram in Math? - Definition & Examples

Watch this video lesson to see how useful a histogram can be when you need to show a bunch of data in an easy to read format. Also, learn how you can easily gather the information you need from looking at a histogram.

What are Center, Shape, and Spread?

6. What are Center, Shape, and Spread?

Center, shape, and spread are all words that describe what a particular graph looks like. Watch this video lesson to see how you can identify and explain each.

Describing the Relationship between Two Quantitative Variables

7. Describing the Relationship between Two Quantitative Variables

In this video lesson, you will learn about quantitative variables, what they are, and how one variable relates to another. You will learn why this is important and why it can sometimes even save lives.

Reading and Interpreting Line Graphs

8. 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.

Making Estimates and Predictions using Quantitative Data

9. Making Estimates and Predictions using Quantitative Data

Watch this video lesson to learn how you can read a scatter plot to learn more about a particular situation. Also learn how you can make estimates within the range of data you have and predict what may happen outside the range of data.

Creating & Interpreting Box Plots: Process & Examples

10. Creating & Interpreting Box Plots: Process & Examples

Box plots are an essential tool in statistical analysis. This lesson will help you create a box plot and understand its meaning. When you are finished, test your understanding with a short quiz!

What is Bivariate Data? - Definition & Examples

11. What is Bivariate Data? - Definition & Examples

In this lesson, you will be learning about the definition and uses of bivariate data. We will also compare and contrast the characteristics of univariate data and bivariate data.

Creating & Interpreting Scatterplots: Process & Examples

12. Creating & Interpreting Scatterplots: Process & Examples

Scatterplots are a great visual representation of two sets of data. In this lesson, you will learn how to interpret bivariate data to create scatterplots and understand the relationship between the two variables.

Interpreting the Correlation Coefficient

13. Interpreting the Correlation Coefficient

This lesson explains the process of interpreting and analyzing a correlation coefficient both as a figure and as a context by discussing common and easy to understand examples.

How to Interpret Correlations in Research Results

14. How to Interpret Correlations in Research Results

Perhaps the most common statistic you'll see from psychology is a correlation. Do you know how to correctly interpret correlations when you see them? This lesson covers everything you need to know.

The Relationship Between Variables: Correlation Coefficient & Scatterplots

15. The Relationship Between Variables: Correlation Coefficient & Scatterplots

The focus of this lesson is on how both correlation coefficients and scatterplots convey the same message. Specifically, this lesson will explore how these two can reveal the same information but in different ways.
