The document describes an experiment to test if toads cause warts. It involves dividing 300 young people who have never had warts into 3 groups. Group 1 would hold toads for 5 minutes, Group 2 for 3 minutes, and Group 3 would not touch toads. The presence of warts after the experiment would be the response variable. Random assignment, blocking by gender, and blinding the participants about the real purpose would help make the experiment more reliable. However, concerns include upsetting participants if they develop warts, and difficulty finding people willing to hold toads. The conclusion is that this experimental design does not support the theory that toads cause warts, as no warts appeared in any participants.

1. Toads Cause Warts
HYUNWOO GYUNG

2. Experimental Units
 Young people who does not have or had Warts

3. Explanatory Variable
 The toads are the explanatory Variable

4. Treatment
 I will make 3 groups and each of the 3 groups will have 300 people
in them. One group will hold the toads for 5 minutes the second will
hold it for 3 minutes and the third group will not touch it at all.

5. Response Variables
 Would result in the experimental units to get warts

6. Experimental Design
There will be 300 experimental units and 3 groups in this design. Group
1 Group 2 and Group 3 with 100 people in each. Group 1 will receive a
treatment where they will have to touch the toad for 5 minutes. Group
2 will have the treatment and they will have to touch the toad for 3
minutes. Group 3 will have no treatment at all.
300 People
100 Touch 5 Min
100 touch 3 Min
100 don’t touch
Presence of
Warts

7. Experimental Design Principals
 The control group is 100 young people who does not have or had
warts just like the other groups except they don’t touch the toads at
all.
 Randomization in this experimented would be by putting the names
of all the people and the names will be drawn from a hat randomly
and places into a group 1, 2, or, 3.

8. Blocking
 Blocking could be used by making the groups have Males and
Females. So the 3 groups will stay the same, but in each group there
will be 50 males and 50 females. This could be used to see if the
toads causing warts occurs generally to the male or female
population and you could compare it that way through genders.

9. Blinding
Blinding would be used in where the experimental units would be told
they are measuring heart rate while holding the toads for 5, 3 or 0
minutes. SO they won’t know it is to test if it would give them warts so
they can’t think they were getting it and reduces bias in the
experiment.

10. Concerns
 Some concerns in this experiment is that if you tell them that it is to
monitor heart pace and you find out that toads really did cause
warts then people would be really upset that they got warts
because of this experiment. Also another concern would be it is
hard to find young people who didn’t have warts to hold frogs
because as far as I know not many people likes to hold toads.

11. Conclusion
 In conclusion the information does not support the theory of toads
causes warts because out of all the 300 people not one person got
warts. Further study could be done where there are other kind of
studies behind the scenes to make it possible.
