Prism 9 Bubble Plot Features

In this video, Jim Colton from GraphPad introduces the new bubble plot feature in Prism 9, which utilizes the categorical variable feature in multiple variables data tables. The bubble plot is an enhanced version of the xy scatter plot, allowing for two additional dimensions represented by symbol color and size. The video demonstrates how to create a life expectancy versus birth rate bubble plot, customize its appearance, and handle overlapping symbols using semi-transparent color schemes. It also covers adding labels and making final adjustments to improve data visualization.

What is a unique feature of the new bubble plot in Prism 9 compared to a traditional scatter plot?

• It is limited to categorical variables.

• It uses only two variables.

• It does not support continuous variables.

• It can represent four variables, including color and size.

How does Prism 9 simplify the entry of categorical variables in a data table?

• By allowing direct text entry like 'male' and 'female'.

• By requiring binary coding of variables.

• By using only numeric codes.

• By automatically converting text to numbers.

In the example bubble plot, what does the size of the plotting point represent?

• Life expectancy

• Birth rate

• Country population

• Continent

What issue might arise with the symbols in the population size legend?

• They are too small to be visible.

• They are too big to be shown at their true size.

• They are not colored correctly.

• They do not appear on the graph.

What feature does Prism 9 offer to handle overlapping symbols in a bubble plot?

• Increasing the size of all bubbles.

• Removing some bubbles.

• Using semi-transparent color schemes.

• Changing the graph type.

How can you adjust the size of bubbles in a Prism 9 graph?

• By using a different color scheme.

• By double-clicking on the graph and adjusting settings.

• By changing the graph type.

• By altering the data table.

What is the purpose of using semi-transparent color schemes in a bubble plot?

• To make the graph more colorful.

• To change the background color.

• To handle overlapping symbols.

• To highlight specific data points.

What relationship is observed between birth rate and life expectancy in the bubble plot?

• Higher birth rate correlates with higher life expectancy.

• Higher birth rate correlates with lower life expectancy.

• No correlation is observed.

• Life expectancy is independent of birth rate.

What can be done to improve the visibility of labels in a crowded bubble plot?

• Reduce the number of labels.

• Expand the graph by clicking and dragging on the axes.

• Change the color of the labels.

• Remove all labels.

What is one of the new features in Prism 9 mentioned in the video?

• Estimation plot

• Bar chart

• Pie chart

• Line graph
