Exam 3: Visual Displays of Data

A student poll on your university website for athletics asks, "How high do you think the basketball team will finish this year: 1st, 2nd, 3rd, 4th, or 5th?" An article posted a week later reports "Students predict basketball team to finish within the top 5 out of 16 teams in the conference." What kind of manipulation occurred here?

In a pie chart, each slice represents a level on the _____ variable.

Pictorial graphs are sometimes used when the independent variables has _____ categories.

What should be kept in mind when organizing data in graphs?

In the _____ lie participants in a study are preselected, resulting in biased results.

A graph that depicts the relation between two scale variables is a:

If graphing one scale independent variable and one scale dependent variable, use a:

Any background pattern on which graphs appear is a form of chartjunk called:

A scatterplot with a line of best fit is known as a time line plot.

Use the following to answer questions This figure depicts the typical relation found between a person's age (in years) and his or her reaction time in a simple reaction time task (e.g., time to press a button when a light turns green). Figure: Age and Reaction Time -(Figure: Age and Reaction Time) Based on the graph, what type of relation exists between age and reaction time?

The first step in creating a scatterplot is to:

Use the following to answer questions Figure: Class Rank -(Figure: Class Rank) Based on this graph, what type of relation exists between freshman class rank and senior class rank?

If graphing one nominal independent variable and one scale dependent variable, use a:

When constructing a graph, it is better to make one's own, intentional decisions about its appearance than to rely on computer:

What is a potential benefit of creating a Pareto chart rather than a bar graph?

When reading a graph, one of the first questions you should ask yourself is what is being predicted, or what the _____ variable is.

A researcher was interested in measuring reaction time differences between men and women on a computerized task.What is the dependent variable?

A time plot is also known as a:

The lie of interpolation assumes that values beyond the data points will continue indefinitely, while the lie of extrapolation assumes that some value between the data points lies on a straight line between those data points.

The Pareto chart is a type of bar graph.
