Introductory Mathematics
Data Analysis and Probability:
COMPETENCY GOAL 3: The learner will understand and use graphs and data analysis.
Calculating...
Lesson  (...)
Lesson: Students discover algorithms as they sort shapes into Venn diagrams. Then students compare the efficiency of their algorithms using box plots.

Lesson: Introduces students to quartiles and box plots.

Lesson: Introduction and fine points of using bar graphs and histograms.

Lesson: This lesson allows students to learn what bar graphs are used for, how to interpret the data presented, and how to organize their own data using bar graphs.

Lesson: Introduces statistical measures of center.

Lesson: 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.

Lesson: Looks at statistics and data analysis concepts from the practical questions that arise in everyday life.

Lesson: Introduces students to stem-and-leaf plots and calculating the mean, median, and mode from the plots.

Lesson: Students learn about the difference between univariate and bivariate data and understand how to choose the best graph to display the data.

Activity  (...)
Activity: Enter data to create a bar graph, then change many settings for the graph's appearance.

Activity: Students can create box plots for either built-in or user-specified data as well as experiment with outliers. User may choose to use or not use the median for calculation of interquartile range.

Activity: 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.

Activity: View histograms for built-in or user-specified data. Experiment with how the size of the class intervals influences the appearance of the histogram. Parameters: Data sets, class sizes.

Activity: Enter data to create a double bar graph, then manipulate the graph's maximum and minimum values.

Activity: 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.

Activity: 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.

Activity: 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.

Activity: View stem-and-leaf plots of your own data, and then practice finding means, medians and modes. Stem and Leaf Plotter is one of the Interactivate assessment explorers.
