What is a Box and Whisker Plot?

Statistics come front and center in this unit all about analyzing discrete data. Real-world situations yield data sets that the class then uses to tease out connections and conclusions. Beginning with the basic histogram and...

Analyze data using technology. Middle schoolers design data investigations, describe data, and draw their own conclusions. Then they select the best type of graph, graph and interpret the data, and look for patterns in trends. They also...

Learners explore the concept of univariate and bivariate data. In this univaritate and bivariate data lesson, pupils discuss the differences between univariate and bivariate data. They work sample problems where they must construct box...

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...

Middle and high schoolers examine how data squares organize and sort information and data sets. They discuss examples of data squares, complete a data square about themselves, organize the data squares for the class together, and compile...

You already know that the mode of a data set is the number that occurs most often in the set. But what if all of the numbers in the set occur the same number of times? I could tell you the answer, but I think you should watch the video.

You already know that the mode of a data set is the number that occurs most often in the set. But what if all of the numbers in the set occur the same number of times? I could tell you the answer, but I think you should watch the video.

Mode, the number that occurs most often. A data set could have one mode, no modes, or multiple modes. The teacher explains these variations and even gives some example of non-numerical data and how to figure out the mode.

Not all data is the same. Using the interactive, pupils compare data represented in two different ways. The learners develop an understanding of the difference between discrete and continuous data and the different ways to represent each...
