Data, Statistics & Graphs - Chapter Summary
If you want to ensure that you comprehend data, statistics and graphs, this chapter can help! Lessons developed by top instructors provide a comprehensive overview of how data and statistics are calculated and then displayed in the form of graphs. Access these lessons anytime from your smartphone, tablet or computer. Once finished with this chapter, you will be ready to do the following:
- Demonstrate how to calculate the probability of dependent and independent events
- Calculate simple conditional probabilities
- Show how to apply conditional probability and independence to real-life situations
- Differentiate between mean and median
- Exhibit an ability to evaluate independence using two-way tables
- Describe how to interpret graphical representations
- Define scatterplots, line graphs and the histogram in math
- Explain the process of creating and interpreting dot plots and box plots
All of the lessons in this chapter can be accessed in video and full transcript formats. Watch the videos to enjoy a visually entertaining review of data, statistics and graphs, and take advantage of the ability to print and take additional notes on the full transcripts. Before, during or after reviewing these lessons, feel free to test your knowledge by taking short self-assessment quizzes. If you answer any questions incorrectly, click the link next to the answer to revisit the related portion of the video lesson.
1. Probability of Independent and Dependent Events
Sometimes probabilities need to be calculated when more than one event occurs. These types of compound events are called independent and dependent events. Through this lesson, we will look at some real-world examples of how to calculate these probabilities.
2. How to Calculate Simple Conditional Probabilities
Conditional probability, just like it sounds, is a probability that happens on the condition of a previous event occurring. To calculate conditional probabilities, we must first consider the effects of the previous event on the current event.
3. Applying Conditional Probability & Independence to Real Life Situations
It can be really confusing learning how to apply conditional and independent probability to real-life situations. This lesson focuses on several examples and practice problems to help you learn how to find conditional probability.
4. 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?
5. Using Two-Way Tables to Evaluate Independence
If you are a visual person, a 2-way table is a great way to analyze information. This lesson shows you how to use a 2-way table to determine the independence of variables.
6. Interpreting Graphical Representations
After watching this video lesson, you will be able to quickly and easily read and interpret any line and bar graph. You will be able to gather important information by just looking at one of these graphs.
7. 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.
8. 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.
9. Creating & Interpreting Dot Plots: Process & Examples
Dot plots are a visual way to display the frequency distribution in a data set. In this lesson, you will learn how to construct a dot plot and understand its uses.
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!
