Simpsons Experimental Design
Smithers thinks that a special juice
will increase the productivity of
workers. He creates two groups of
50 workers each and assigns each
group the same task (in this case,
they're supposed to staple a set of
papers). Group A is given the special juice to drink while
they work. Group B is not given the special juice. After
an hour, Smithers counts how many stacks of papers
each group has made. Group A made 1,587 stacks,
Group B made 2,113 stacks.
,
Identify the:
1. Control Group
Group B
2. Independent Variable
volume of special juice
3. Dependent Variable
number of stapled packs of paper
4. What should Smithers'
conclusion be?
The special juice interferes with
the workers productivity since
Group A stapled fewer packets
than group B.
5. How could this experiment be
improved?
Vary the volume of juice given,
increase the sample size, take
more time points, conduct the
experiment for a longer period of
time.
Homer notices that his shower is
covered in a strange green slime.
His friend Barney tells him that
coconut juice will get rid of the
green slime. Homer decides to
