About This Chapter
FTCE Math: Sampling Statistics - Chapter Summary
Explore the various kinds of sampling methods and determine how each one can be used to gather data. The lessons will differentiate between sampling methods and explain when it's best to use any particular technique. One lesson will clarify the law of large numbers, which can sometimes be confusing. Another lesson will highlight the importance of non-representative samples as well as non-response bias and voluntary bias in sampling. You can also learn about the two categories of biases. Check out this chapter in order to:
- Define and use the simple random sampling method
- Identify the conditions and measures of random sampling
- Describe the characteristics of stratified, cluster and systematic random samples
- Explain the law of large numbers
- Understand selection and response biases in statistics
Prepare for the FTCE Math examination with this chapter. The video lessons are ideal for those who like to learn through colorful animation and graphics, but they also contain material for learners who enjoy the reading aspect of learning. Bold terms are explained, sampling methods are detailed and interesting examples are provided in the written transcripts. The lessons are short, and you can learn as much information at a time as you're comfortable with. Experts provide the videos' narrative voices, and they'll answer the questions that you submit about sampling statistics.
1. Simple Random Samples: Definition & Examples
Simple random sampling is a common method used to collect data in many different fields. From psychology to economics, simple random sampling can be the most feasible way to get information. Learn all about it in this lesson!
2. What is Random Sampling? - Definition, Conditions & Measures
Random sampling is used in many research scenarios. In this lesson, you will learn how to use random sampling and find out the benefits and risks of using random samples.
3. Stratified Random Samples: Definition, Characteristics & Examples
Random sampling isn't always simple! There are many different types of sampling. In this lesson, you will learn how to use stratified random sampling and when it is most appropriate to use it.
4. Cluster Random Samples: Definition, Selection & Examples
Cluster random sampling is one of many ways you can collect data. Sometimes it can be confusing knowing which way is best. This lesson explains cluster random sampling, how to use it, and the differences between cluster and stratified sampling.
5. Systematic Random Samples: Definition, Formula & Advantages
Systematic random sampling is a great way to randomly collect data on a population without the hassle of putting names in a bag or using a random number generator. In this lesson, learn all about how and when to use systematic random sampling.
6. Understanding the Law of Large Numbers
The law of large numbers is a concept that is often misunderstood in statistics. In this lesson, you will learn the real meaning of the law of large numbers and how it is employed.
7. Bias in Statistics: Definition & Examples
Statistics can be a powerful tool in research. Unfortunately, statistics can also have faults. In this lesson, you will learn about the faults in statistics and how to critically examine potential biases in research.
