Explore the idea of a confidence interval where it is easier to predict that an unknown value will lie somewhere within a wide range, than to predict it will occur within a narrow range.

Students learn about confidence intervals. Topics explored are the Central Limit Theorem, large sample confidence intervals, and confidence intervals for small samples. The tutorial investigates the statistics concept through class notes...

This set contains questions about statistics regarding confidence intervals for means. Students analyze the relationship, concerning means, between confidence levels and the length of confidence intervals.

In this activity, students estimate statistical measures and find confidence intervals.

The fastest route to confidence is to stop being so attached to one's dignity and seriousness; and plainly admit that one is an idiot. The School of Life explains. [5:03]

Based off of the hit television show NUMB3RS, this lesson introduces students to confidence intervals by using a simulation. Students use a calculator (or random number table) to simulate a situation with a certain success rate, and then...

This set contains questions about statistics involving how to choose a sample size to fit a desired maximum error bound. The student learns to do this on confidence intervals for proportions as well as confidence intervals for means.

In this activity, students test if a significant relationship exists between a bivariate data set, and then calculate the confidence and predictive intervals. They also improve the interval-prediction capabilities by automating the process.

Students understand how tests of significance can be performed with confidence intervals. They use a simulation to clarify the meaning of a hypothesis. Students examine large sample tests for a proportion, mean, difference between two...
