Data Analysis and Data Explorer

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...

Represent data graphically. Allow your class to explore different methods of representing data. They create foldables, sing songs, and play a dice game to reinforce the measures of central tendency.

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.

Mean, mode, median? What's the difference? How do you find them? The teacher focuses on explaining median in this video. She gives a good explanation and shows how to order a data set to find the median number. This given data set has an...

There are eight decimals numbers in this data set. Find the mean. So add all the terms together and then divide that total number by the number of terms in the data set. That's how you find the mean or average of a data set.

Looking for the range of a set of numbers? Well, that means you are looking for the difference between the largest value and the smallest value. So first, write the numbers in order from least to greatest. Then identify the largest value...

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.
