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:
This is the ID number of the participant
·
See_Distance:
This is participants’ anxiety (scores could range from 40 to 100, with high
numbers indicating higher anxiety) when they saw a large snake that was about
20 feet away.
·
See_Close:
This is participants’ anxiety (scores could range from 40 to 100, with high
numbers indicating higher anxiety) when they saw a large snake that was about 5
feet away.
·
Touch: This
is participants’ anxiety (scores could range from 40 to 100, with high numbers
indicating higher anxiety) when they touched a large snake.
