Examples of Gunpowder Plot in the following topics:
-
The First Stuarts and Catholicism
- On the eve of the state opening of the parliamentary session on November 5, 1605, a soldier called Guy Fawkes was discovered in the cellars of the parliament buildings guarding a pile of slaves, not far from about twenty barrels of gunpowder with which he intended to blow up Parliament House the following day and cause the destruction.
- A Catholic conspiracy led by a disaffected gentleman called Robert Catesby, the Gunpowder Plot, as it quickly became known, had in fact been discovered in advance of Fawkes's arrest and deliberately allowed to mature in order to catch the culprits red-handed and the plotters unawares.
-
Contour Plots
- Contour plots portray data for three variables in two dimensions.
- The plot contains a number of contour lines.
- Each contour line is shown in an X-Y plot and has a constant value on a third variable.
- An alternative way to draw the plot is shown in Figure 2.
- A contour plot showing calories as a function of fat and carbohydrates
-
3D Plots
- Just as two-dimensional scatter plots show the data in two dimensions, 3D plots show data in three dimensions.
- Figure 1 shows a 3D scatter plot of the fat, non-sugar carbohydrates, and calories from a variety of cereal types.
- Interactively rotating 3D plots can sometimes reveal aspects of the data not otherwise apparent.
- A 3D scatter plot showing fat, non-sugar carbohydrates, and calories from a variety of cereal types
- An alternative 3D scatter plot showing fat, non-sugar carbohydrates, and calories.
-
Dot Plots
- Judge whether a dot plot would be appropriate for a given data set
- Dot plots can be used to display various types of information.
- The dot plot in Figure 3 shows the number of people playing on a Sunday and on a Wednesday.
- A dot plot showing the number of M & M's of various colors in a bag of M & M's.
- A dot plot showing the number of people playing various card games on a Wednesday.
-
Plotting Points on a Graph
- The plot can be drawn by hand or by a mechanical or electronic plotter.
- Graphs can also be used to read off the value of an unknown variable plotted as a function of a known one.
- Plots play an important role in statistics and data analysis.
- As an example of plotting points on a graph, consider one of the most important visual aids available to us in the context of statistics: the scatter plot.
- The researcher would then plot the data in a scatter plot, assigning "lung capacity" to the horizontal axis, and "time holding breath" to the vertical axis.
-
Segmented bar and mosaic plots
- A segmented bar plot is a graphical display of contingency table information.
- Examine both of the segmented bar plots.
- A mosaic plot is a graphical display of contingency table information that is similar to a bar plot for one variable or a segmented bar plot when using two variables.
- Figure 1.39(a) shows a mosaic plot for the number variable.
- The one-variable mosaic plot for number and the two-variable mosaic plot for both number and spam.
-
Statistical Graphics
- Statistical graphics allow results to be displayed in some sort of pictorial form and include scatter plots, histograms, and box plots.
- They include plots such as scatter plots , histograms, probability plots, residual plots, box plots, block plots and bi-plots.
- Many familiar forms, including bivariate plots, statistical maps, bar charts, and coordinate paper were used in the 18th century.
- A scatter plot helps identify the type of relationship (if any) between two variables.
-
Graphing Quantitative Variables
- The upcoming sections cover the following types of graphs: (1) stem and leaf displays, (2) histograms, (3) frequency polygons, (4) box plots, (5) bar charts, (6) line graphs, (7) scatter plots, and (8) dot plots.
- Graph types such as box plots are good at depicting differences between distributions.
- Scatter plots are used to show the relationship between two variables.
-
Exercises
- For the following data, plot the theoretically expected z score as a function of the actual z score (a Q-Q plot).
- For the "SAT and College GPA" case study data, create a contour plot looking at College GPA as a function of Math SAT and High School GPA.
- For the "SAT and College GPA" case study data, create a 3D plot using the variables College GPA, Math SAT, and High School GPA.

Graphs for Quantitative Data
- A plot is a graphical technique for representing a data set, usually as a graph showing the relationship between two or more variables.
- Graphs can also be used to read off the value of an unknown variable plotted as a function of a known one.
- Plots play an important role in statistics and data analysis.
- Below are brief descriptions of some of the most common plots:
- This kind of plot is also called a scatter chart, scattergram, scatter diagram, or scatter graph.
