An Overview of the Data Set

This data set represents hypothetical data from a study that examined the level of anxiety that people with a snake phobia felt in three different scenarios. The same people were tested in each scenario. That is, each person experienced all three conditions.

Here is some more information about the variables in this hypothetical data set:

• Number: The participant's ID number
• See_Distance: The participant's anxiety (scores could range from 40 to 100, with high numbers indicating higher anxiety) when they saw a large snake from about 20 feet away
• See_Close: The participant's anxiety (scores could range from 40 to 100, with high numbers indicating higher anxiety) when they saw a large snake from about 5 feet away
• Touch:The participant's anxiety (scores could range from 40 to 100, with high numbers indicating higher anxiety) when they touched a large snake
