It's Electric
#1
None of Mr. Lehman’s students were
doing their homework. Mr. Lehman wanted to do an experiment to try
and get his students to do their homework.
He decided that he would
give an electric shock to each of his classes that did not do their homework.
He wanted to know if a class that was given electric shock would be more
likely to do their homework.
#2
He went to the library and read several
studies about the effects of electric shock on lab rats. The lab
rats were more likely to do a given task when they were shocked with high
voltages of electricity.
#3
He guessed that the more electric
shock that his students were subjected to, the more they would do their
homework.
#4
He divided his students into
5 groups. The groups were all the same size, had the same number
of boys and girls, and were all the same ability level.
-
Group #1 was not given any electric
shock when they did not do their homework
-
Group #2 was given 50 volts of electric
shock when they did not do their homework.
-
Group #3 was given 100 volts of electric
shock when they did not do their homework.
-
Group #4 was given 150 volts of electric
shock when they did not do their homework.
-
Group #5 was given 200 volts of electric
shock when they did not do their homework.
#5
-
Group #1 still did not turn in any
of their homework
-
Group #2 turned in their homework 25%
of the time.
-
Group #3 turned in their homework 50%
of the time.
-
Group #4 turned in their homework 75%
of the time.
-
Group #5 turned in their homework 100%
of the time.
