Instructions

Play through this interactive game to learn about Summarize Data By Data Collection Measures. Suitable for Grade 6, Grade 7, Grade 8.

Main Concepts

Center is measured by the median, a number arrived at by counting to the middle of an ordered array of numerical data.

See the center of the data as the middle of the data set.

Display data generated from statistical questions with dot plots (or line plots), histograms (appropriate for large data sets).

Describe the spread of the data (between shapes and from start to end of the data set).

When the data set is even the median will be the average of the two middle numbers.

Quartiles are the medians of the lower and upper halves of the ordered data values - quartiles describe the spread of the data and are found in the same manner as finding the median by finding the middle number of both halves of the data as separated by the median.

The quartiles separate the data into 4 sections that each contain the same amount of data points but vary in shape and size.

Box plots organize data into a display that shows how the shape of the data can be compared. The data is organized into 5 points; the minimum or least data point from the entire set, median, the first quartile or median of the bottom 50% of data, third quartile or median of the top 50% of the data set and the maximum or the highest value of the data set.

Discussion Questions

Before the Game

When working with a data set and statistics, what is a quartile and what does it show? Why would we want to analyze a data set? What are some ways that we can visually represent data? Why is it important to collect statistics in the game of basketball, for example? What is a median? To show off your skills, arrange following numbers from lowest to highest and find the median: 28, 15, 33, 52, 29.

After the Game

How do we find the median in a data set that contains an even number of items? How would you describe the skew of the data? How can you tell if data is skewed right or skewed left? In a dot plot, how do we know if the data is symmetrical? What is the procedure for creating a box and whiskers plot from a set of data? After playing this game, do you feel more knowledgeably about quartiles and what they represent and how to find them in a data set?
