So you have a data set and you want a visual diagram to help you analyze the data. Not sure how to draw it? The instructor illustrates four different ways to look at a frequency table: two tally tables, one line graph, and one bar graph....

So you have a data set and you rewrite the numbers in order from least to greatest. You find that there are two number values that occur twice in the set. Oh no, mode means the number that occurs the most times in a set. Now what do you...

The teacher gives a very thorough explanation of numerical or quantitative data being anything where the answer to a question would be a number. Whereas any other answer might be considered categorical. She shows several different ways...

The data sample comes from the number of glasses of water consumed each day by 15 students. You are trying to find minimum, maximum, median, and quartile from this data set. Minimum is the smallest number that occurs, while maximum is...

If the y-value decreases as the x-value increases then you have a negative correlation. Meaning that the line-of-fit has a negative slope.

What is a line-of-fit? Given a data set, plot the ordered pairs on a graph. It looks like a scatter plot. Now estimate, and draw a line that best fits what the data represents. That is your line-of-fit.

Kurtosis is a measure of weather data is peaked or flat. It will be displayed as a curve with long tails and a high peek. Each of the various kurtosis curves of distribution are describes and explained.

Help your class study for the next exam with this easy-to-follow video. They will see how the tutor uses a histogram to determine a sum that answers a question based on the information found on the histogram.

Learners won't have a hard time reading the data on a line graph after viewing this comprehensive video clip. The tutor speaks slowly and clearly so that learners will be able to follow along as she answers a two-part question with data...

Draw a line plot along with the tutor in this super slow video. The tutor speaks extra slow and extra clear so that learners can easily understand the process needed to draw a line plot or pictograph. Send this link home to help learners...

Bar graphs can help learners answer questions, such as the difference between speed limits. Using the data collected and displayed on a bar graph, the tutor reads the given speed limits to pull data, subtract, and find the difference....

If the y-value increases as the x-value increases then you have a positive correlation. Meaning that the line-of-fit has a positive slope.

If the y-value decreases as the x-value increases then you have a negative correlation. Meaning that the line-of-fit has a negative slope.

What is a line-of-fit? Given a data set, plot the ordered pairs on a graph. It looks like a scatter plot. Now estimate, and draw a line that best fits what the data represents. That is your line-of-fit.

A look at why multivariate data is collected and how it can be graphed by a computer program for study analysis. The real-life example shown here involves collecting and analyzing data taken from the Chesapeake Bay in order to examine...

Swinging back and forth, the solo trapeze is a giant pendulum, just like the one in a grandfather clock. The time it takes to swing forward, then back to where it started is called the period. Surprisingly, this time has very little to...

This QuickTime movie provides an opportunity to create a data table by analyzing a scatter plot. As you watch and listen to the teacher and student interact it helps clarify the thinking behind applying this concept.

Video serves as an introduction to frequency tables which tell you how often something occurs in a set of data. [6:44]

This video discusses how to determine whether the results of a statistical experiment can be generalized to a larger population. Includes downloadable study guide with exercises - guide also covers other topics. [5:07]

From the MathFLIX Series, this Quick-Time movie builds on student knowledge of the concepts of mean, median, and mode. In this interactive discussion, teacher and student go step by step through the data analysis process to identify...

Students process and analyze data on traffic light congestion. This is part of a 7-part engineering design lesson. [3:31]

This course is designed to help users gain an understanding of Data, learn about different types and attributes of data, and help them understand why this information is important in the world today. Includes two videos (25 min....

The resource from Khan Academy provides practice questions for the SAT. Watch Sal work through a harder Center, spread, and shape of distributions problem.

In this lesson, students see how to write a summary based on a set of data. It is 4 of 6 in the series titled "Writing a Data Summary." Includes short quiz. [3:33]
