There's any number of reasons why number lines are important. Young mathematicians learn about two skills related to numbers lines. First, they see how to determine the value of a point by considering the intervals drawn on the number...

Close the chapter on extrema on a closed interval. Watching an informative video provides scholars with an opportunity to learn about extrema. Specifically, they see how to find the global maxima and minima on a closed interval by first...

Rounding a number sometimes creates more problems. A video lesson explains the error intervals for rounded and truncated numbers. The narrator expresses the error as a compound inequality and uses a number line as a reference.

If the shoe fits, include it in the display. The presentation uses shoe size to introduce organizing data within a frequency table and a histogram. Using another histogram, the video outlines how to interpret the data display. To...

Just how fast is the function changing? The presenter provides a general explanation of the average rate of change in the 28th presentation in a series of 31 calculus videos. The video moves on to find the average rate of change for a...

Explore the effect sample size has on margin of error and confidence interval. The instructor calculates the margin of error of fictional data. He shows how the calculation changes when the sample size changes while keeping the other...

Frequency polygons are a different way to represent frequencies over intervals. Pupils take frequencies for intervals of data from a frequency table and plot them as a frequency polygon. Budding mathematicians find information about the...

Explore the meaning of the margin of error and how to use it to calculate the confidence interval with a video that explains how to calculate a margin of error based on the sample size. The instructor also makes a connection between...

Develop an expert (not intermediate) understanding of the Intermediate Value Theorem with a video that teaches young mathematicians about the Intermediate Value Theorem. It introduces the idea of proving that a root exists in an...

Utilize Excel software to analyze a set of data by making statistical calculations. The instructor shows how to find the standard deviation, mean, minimum, maximum, margin of error, confidence intervals, and range using Excel commands....

Teach how to find a confidence interval from a population proportion and margin of error with a video that reviews how to find a population proportion and a margin of error. The instructor then explains how to create a confidence...

Introduce the concept of domain and range with a video that starts with the formal definitions of the domain and range and moves on to the practical descriptions used to determine them. The presentation explains how to find the domain...

Physics and math are closely associated in the science community. High schoolers use information in the video to determine how derivatives and calculus help them understand our local environment. They complete problems that relate to...

Viewers os this short video learn how to prove that a root exists in a given interval without having to determine the actual value of the root. Applying the Intermediate Value Theorem is most helpful in this situation.

Explains the features of histograms, when they are useful, and the statistical vocabulary that is used when describing them. Also models how to compare and contrast distributions. Includes downloadable study guide with exercises - guide...
