Curated OER
Business & Statistics: Final Exam
In this business and statistics worksheet, learners read real-life business problems, arrange data, and identify the probability method best used to determine the answer. They identify the type of random sample, draw stem-and-leaf plots,...

Texas Gateway: A Single Population Mean Using the Normal Distribution
This lesson explains how to calculate and interpret the confidence interval for a population mean. It also looks at the effect on the confidence interval of changing the confidence level or sample size. It then explains how to find the...

Texas Instruments: Numb3 Rs: Thumbs Up!
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...

Bellevue: Accuracy vs. Precision & Error vs. Uncertainty
A really nice distinction here in this longish piece from the Bellevue Community College. It's not just accuracy vs. precision, but also error vs. uncertainty. This is a necessary additional consideration for any paper on the topic.

Khan Academy: Interpreting Confidence Levels and Confidence Intervals
When we create a confidence interval, it's important to be able to interpret the meaning of the confidence level we used and the interval that was obtained.

Khan Academy: Interpreting a Z Interval for a Proportion
Once we build a confidence interval for a proportion, it's important to be able to interpret what the interval tells us about the population, and what it doesn't tell us. Let's look at few examples that demonstrate how to interpret a...

Khan Academy: Reference: Conditions for Inference on a Proportion
When we want to carry out inferences on one proportion (build a confidence interval or do a significance test), the accuracy of our methods depend on a few conditions. Before doing the actual computations of the interval or test, it's...

Khan Academy: Making a T Interval for Paired Data
In some studies, we make two observations on the same individual. For instance, we might look at each student's pre-test and post-test scores in a course. In other studies, we might make an observation on each of two similar individuals.

Khan Academy: Interpreting a Confidence Interval for a Mean
After we build a confidence interval for a mean, it's important to be able to interpret what the interval tells us about the population and what it doesn't tell us.
