Box-and-Whisker Plots
Construct a box‑and‑whisker plot to match a line plots, and construct a line plot to match a box‑and‑whisker … plots. Manipulate the line plot and examine how the box‑and‑whisker plot changes. Then manipulate the box‑and‑whisker plot and examine how the line plot changes.

Center of Mass
Drag blocks onto a two-dimensional surface and observe the effects on the center of mass. Use a grid to calculate the coordinates of … the center of mass. Investigate predefined shapes or your own arrangements of blocks.

Constructing Box-and-Whisker Plots
Construct a box‑and‑whisker plot to match a line plots, and construct a line plot to match a box‑and‑whisker … plots. Manipulate the line plot and examine how the box‑and‑whisker plot changes. Then manipulate the box‑and‑whisker plot and examine how the line plot changes.
-
Correlation
Explore the relationship between the correlation coefficient of a data set and its graph. Fit a line to the data and compare the … least-squares fit line.
-
Describing Data Using Statistics
Investigate the mean, median, mode, and range of a data set through its graph. Manipulate the data and watch how the mean, median, mode, … and range change (or, in some cases, how they don't change).
-
Exploring Data Using Histograms
Build a data set and compare its histogram to its line plot. Vary the size of the intervals and explore how the histogram changes in response.
-
Histograms
Change the values in a data set and examine how the dynamic histogram changes in response. Adjust the interval size of the histogram and … see how the shape of the histogram is affected.
-
Line Plots
Build a data set using a line plot. Find its mean, median, mode, and range. Change the data values by dragging the points, and watch how … the mean, median, mode, and range change (or, in some cases, do not change).

Lines of Best Fit Using Least Squares - Activity A
Fit a line to the data in a scatter plot using your own judgment. Then compare the least squares line of best fit.
-
Lines of Best Fit Using Least Squares - Activity B
Fit a line to the data in a scatter plot using your own judgment. Then compare the least squares line of best fit.
-
Mean, Median and Mode
Build a data set and find the mean, median, and mode. Explore the mean, median, and mode illustrated as frogs on a seesaw, frogs on a … scale, and as frogs stacked under a bar of variable height.
-
Scatter Plots - Activity A
Examine the scatter plot for a random data set with negative or positive correlation. Vary the correlation and explore how correlation … is reflected in the scatter plot and the trend line.
-
Scatter Plots - Activity B
Examine the scatter plot for a random data set with negative or positive correlation. Vary the correlation and explore how correlation … is reflected in the scatter plot and the trend line.
-
Solving Using Trend Lines
Examine the scatter plots for a data related to weather at different latitudes. The Gizmo includes three different data sets, one … with negative correlation, one positive, and one with no correlation. Compare the least squares best‑fit line.
