New ReviewTry to find the middle of a frequency table. Using a frequency table of ages, the video shows how to use a formula to determine the position of the median. The resource uses frequency tables with both even and odd numbers of data points.

New ReviewFind the one in the middle. An informative resource explains how to determine the median of a set of numbers. Using both even and odd numbers of data points, the video covers the process of finding the middle number. Worksheets provide...

New ReviewSpread the data out on the range. The short video provides a definition of the range. Using a data set of five numbers, the resource calculates the range.

New ReviewMost frequently prefer the mode. The resource defines the mode and shows how to determine it in a data set. Using another type of problem, the video develops a data set with a given mode and number of data points.

New ReviewCan scholars determine the mean if the frequency is for a range? By using a method similar to finding the mean from a frequency table, the video shows how to find an estimated mean for grouped data. It uses the midpoint of the interval...

New ReviewWhat makes data big? The 38th installment in the series Crash Course Statistics provides a definition of big data and its origins. It shows various methods and resources on how to collect big data and how companies use big data for a...

New ReviewThe big, the bad, and the ugly of data. The resource picks up from the description of big data and discusses the possible problems. Using examples, the 39th video in the series of Crash Course statistics explains how some use big data...

New ReviewIf 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...

New ReviewKeep the leaves on the stem for mathematical success. Using the lengths of telephone call data, an informative video goes through the steps to create a stem-and-leaf plot. The presenter shows how to read and interpret data in a...

New ReviewLet the machines do what they do best. The 37th installment of the Crash Course Statistics series focuses on unsupervised machine learning. It describes two methods, k-means and hierarchical clustering, and provides examples for each.

New ReviewUse math to help predict the future. Viewers of the 36th Crash Course video covering statistics hear about machine learning. They see how logistic regression, linear discriminant analysis, and K nearest neighbors are all models that help...

New ReviewHow many ways can you think of to display data? A quick video lesson describes the process of creating one of them, a line graph, which is also referred to as a frequency polygon. After creating the graph, the instructor models how to...

New ReviewA conversion graph makes quick work of determining unit conversions. A video lesson demonstrates how to create and use a conversion graph. Learners then demonstrate their understanding with provided practice problems.

New ReviewStacked box plots create an informative visual display. Using a video lesson, scholars compare data from box plots plotted on the same number line. They use both the visual display and the key intervals to make conclusions.

New ReviewBox and whiskers have more to do with data than they do with cats! A video lesson describes how to plot, analyze, and compare box plots. Mathematicians first learn to create a box plot and then how to use information about the quartiles...

New ReviewLearn the ins and outs of creating graphical displays. A video lesson demonstrates the process of creating a bar graph from a frequency table. The instructor models each step including labeling axes, determining intervals, and creating...

New ReviewA statistic of interest is often affected by multiple variables. Continuing from the previous lesson in the Crash Course Statistics playlist, the instructor explains how to apply the ANOVA calculations to multiple variables that have an...

New ReviewHow many ways can you stock a shelf? It's probably more than you think! Young scholars use data in a frequency table to determine how many ways to stock a shelf given a specific constraint for types of groups. They then repeat the task...

New ReviewUnderstanding energy usage requires knowing more than how much energy it takes to charge your cell phone. Scholars learn each text sent uses energy as does each video, game, and phone call. They observe the larger grid of data transfers...

New ReviewTake a serious look at an equally serious topic! Security scholars explore and discuss the methods hackers use to gain access to personal information during a well-written digital citizenship lesson. Part of an extensive series, the...

Making inferences isn't an exact science. Using data about salaries, learners investigate the accuracy of their inferences. Their analyses includes simulations and randomization tests as well as population means.

Chunking information helps you remember that information longer. A hands-on activity tests this theory by having learners collect and analyze their own data. Following their conclusions, they conduct randomization simulations to test...

Reaction rates vary between your dominant and nondominant hand ... or do they? Young scholars conduct an experiment collecting data to answer just that. After collecting data, they calculate the p-value to determine if the difference is...

Public transportation is an important aspect of any growing city. Collaborative groups work to redesign a system for a city in need of restructuring. Young scholars design a route, create a timetable, and incorporate a quality control...
