NCTM
Grades 3-5
Data Analysis and Probability
Select and use appropriate statistical methods to analyze data
Lessons (2)
Students learn what bar graphs are used for, how to interpret the data presented, and how to organize their own data using bar graphs.
This lesson will challenge students to think creatively by having them design and build water balloon catchers from random scrap materials, while requiring them to take into consideration a multitude of variables. Students will then construct at least two bar graphs to be used in a commercial advocating the purchase of their group's catcher.
Activities (6)
Enter data to create a bar graph, then change many settings for the graph's appearance.
Enter your own data categories and the value of each category to create a pie chart. There are also built in data sets which can be viewed.
Enter data and view the mean, median, variance, and standard deviation of the data set. Parameters: Number of observations, range for observations, which statistics to view, identifiers for the data.
Create a pie chart, adjusting the size of the divisions using your mouse or by entering values. Parameters: Number of sections, size of sections, whether to use percents or fractions.
PlopIt allows users to build dot plots of data using the mouse. View how the mean, median, and mode change as entries are added to the plot. Parameters: Range for observations.
Graph ordered pairs and customize the graph title and axis labels. Points are connected from left to right, rather than being connected in the order they are entered.
