You will collect and represent data on a line plot.
After completing this tutorial, you will be able to complete the following:
The Activity Object examines the real-life scenario of taking a survey. Be sure that students are familiar with the concept of a survey. Many examples of surveys can be found in magazines and newspapers. Bring in a few examples to share with the students prior to presenting the Activity Object. Students are introduced to data collection and analysis with a focus on key vocabulary such as, range, mode, outliers, gap, and cluster. After completing the Activity Object, some students may require more exposure to these terms.
Line plot: a graph that shows the frequency of data along a number line
Cluster: the interval of points grouped closely together
The cluster of the above data is 6-9.
Gap: the largest interval where no data occurs
The gap of the above data is 9-15.
Mode: the most repeated data point
The mode of the above data is 8.
Outlier: the point(s) of data relatively isolated from the rest of the data
The outlier of the above data is 15.
Range: the difference between the greatest and least values in a set of data
The range of the above data is 14 (15-1).
