About This Chapter
SAT Math: Data Analysis, Statistics and Probability - Chapter Summary
Use our lessons to review for the statistics and probability portion of your math SAT. Watch the short, informative videos to prepare for test day. Our lessons can help you brush up on the following topics:
- Pie charts and bar graphs
- Mean, median, mode and range
- Geometric sequences
- Probability of combinations and permutations
- Dependent and independent events
- Overlapping and non-overlapping events
After viewing each video, take the short quiz for self-assessment. Then you can revisit any topics that might need more attention.
SAT Math Objectives
The 58 questions in the math section of your SAT assess your ability to use mathematical thinking in solving problems. The data analysis, statistics and probability problems make up 10% to 15% of the math test and analyze your abilities in the following areas:
- Graphs and tables used in data interpretation
- Mean, median and mode in descriptive statistics
The formulas necessary for taking the test are included in the booklet. You won't lose any points for incorrect responses or for questions you choose not to answer.
These lessons can help you meet the SAT math objectives. In addition to the videos and quizzes, this chapter also includes a wealth of practice problems for working with factorial, to make sure that your understanding is firmly in place.
1. 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.
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. Identifying and Calculating Averages on the SAT
In this lesson, we'll take the fear out of averages with a simple explanation and a pattern that you can use to make any average problem simple, even the weighted averages.
4. What is Categorical Data? - Definition & Examples
Categorical data is one of two types of data that you can collect when conducting research. This lesson will teach you how to understand and use categorical data.
5. The Purpose of Statistical Models
Understanding statistics requires that you understand statistical models. This lesson will help you understand the purpose of statistics, statistical models, and types of variables.
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.
7. Defining the Difference between Parameters & Statistics
Using data to describe information can be tricky. The first step is knowing the difference between populations and samples, and then parameters and statistics.
8. What is a Two-Way Table?
Do you believe in Martians? Do you watch football on television? A Two-Way Table or Contingency Table is a great way to show the results of all kinds of survey questions. In this video we will learn how to read a two-way table.
9. How to Calculate Percent Increase with Relative & Cumulative Frequency Tables
In statistics, one way to describe and analyze data is by using frequency tables. This lesson will discuss relative and cumulative frequencies and how to calculate percent increase using these two methods.
10. Probability of Simple, Compound and Complementary Events
Simple, compound, and complementary events are different types of probabilities. Each of these probabilities are calculated in a slightly different fashion. In this lesson, we will look at some real world examples of these different forms of probability.
11. How to Use Scatter Plots to Solve Word Problems
Watch this video lesson to learn how you can use a scatter plot to help you solve a word problem. You will see how easy it becomes to solve your problem once you have your scatter plot.
12. Exponential Growth vs. Decay
How is it that it only takes four years for our computer to go from top-of-the-line to almost worthless? Well, it has something to do with what's called exponential decay, which we'll learn about here!
