Decision Making with Data
Section 8.4
| Activity Name | Activity Description |
|---|---|
| Histogram | Students view histograms for either given or user-specified data sets, and can adjust class interval size. Discussion can focus on how interval size can influence interpretation of the graph. |
| Boxplot | Students view boxplots for either given or user-specified data sets, and can adjust the plot to include outlying data points, and to plot separately by category. |
| Measures | Students use the applet to build a data set and to view relevant statistical measures (mean, median, mode, range, variance and deviation) for the set. |
| Normal Distribution | Students can change the standard deviation of the graphed normal distribution to create a new distribution, allowing them to observe properties like how well the histogram fits the curve and how areas under the curve correspond to the probability that a number is selected. Parameters: standard deviation, number of trials, class intervals. |
| Skew Distribution | Students can change the median standard deviation of the graphed normal distribution to create a skewed distribution, allowing them to observe properties like what it means for the mean, median, and mode to be different. Parameters: median, standard deviation, number of trials, class intervals. |
| PieChart | Students view piecharts. Parameters: Number of sectors, size of sector as a percent. |
