Creating a Line Graph

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...

How do you summarize data that cannot be averaged? Using an exploratory method, learners complete a two-way frequency table on super powers. The subject matter builds upon 8th grade knowledge of two-way tables. 

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...

Take the tediousness out of graphing. Using the interactive tool, learners can efficiently create a line graph from a set of data. They then use the graph to answer questions about specific trends in the data.

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...

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...

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.

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...
