This lesson will introduce the process of sampling. It is 4 of 7 in the series titled "Sampling."

This site from Cornell University contains great information on random or probability sampling. Definitely a site worth checking out on the subject.

This resource explains what generalization is in statistics, its advantages and disadvantages, and problems that can occur, e.g., sample or response bias. Includes detailed examples of sampling error and sample bias.

Teachers can use Smart Exchange to download a SMART Notebook lesson covering the topic of sampling and misleading graphs.

A random sample of 100 learners from a specific high school resulted in 45% of them favoring a plan to implement block scheduling. Is it plausible that a majority of the students in the school actually favor the block schedule? Learners...

This lesson will define the term unbiased sample, and present the different types of unbiased sampling methods (e.g. simple random sample, stratified random sample, systematic random sample). It is 1 of 4 in the series titled "Unbiased...

Sometimes hotels, malls, banks, and other businesses will present a display of a large, clear container holding a large number of items and ask customers to estimate some aspect of the items in the container as a contest. In some cases,...

This site gives a description of a sample (of a population). The page offers information on various types of sampling. There are links to related terms, everyday examples, more information, and the interactive check point involving...

How do you choose the best sampling method for a specific task? This lesson plan asks the learners to decide the best way out of four choices to select three students to serve on a school advisory panel. Learners need to defend their...

Interactive review problems are offered to practice the concepts of random variables and statistics. Topics covered include, Bernoulli trials, normal and binomial distributions, Chebyshev's rule, and the like.

The concept of random variables comes to life with this Applet used to roll one, two, six, or nine dice. The user selects the number of rolls to be completed, and the program quickly counts and graphs the results.

Members of the seventh grade math group have nominated a member of their group for class president. Every student in seventh grade will cast a vote. There are only 2 candidates in the race, so a candidate must receive at least 50% of the...

Members of the seventh grade math group have nominated a member of their group to be class president. Every student in seventh grade will cast a vote. There are 2 candidates in the race and a candidate needs at least 50% of the votes to...

The table below gives the areas (in thousands of square miles) for each of the lower 48 states. This serves as the population for this study. Your task involves taking small samples from this population and using the sample mean to...

This page is a math home page that includes information on all topics of probability and statistics.

This site provides information on the various tests doctors perform during an uncomplicated pregnancy.

This set contains statistics questions regarding surveys and survey designs. The student differentiates between a systematic sample, a convenience sample, a simple random sample (SRS), and a stratified random sample.

Use this applet to practice your estimating skills comparing length, area, counting or a random sampling of those topics. You can also adjust the difficulty and the precision needed. The applet also lets you know how close you are to the...

The list editor provides a means for viewing, editing, and working with data lists. Students can explore distributions, tests, intervals, multiple regression, random sampling, goodness of fit and inferential statistics.

In this activity, students work in groups to collect data and draw conclusions from random samples simulated by drawing tiles from a bag. They represent the data collected in the form of a triple bar graph.
