Only answer if you will mark !
1.the term trial refers to
a. doing an experiment once
b. something that will lead to an error
c. judging whether an experiment is good
d. trying a different procedure for your experiment

2.if you wanted to repeat your experiment, you could do it once, then do it again, and so on. you could also
a. complete more than one trial at once
b. pick a procedure that takes less time to complete
c. ask another group of scientists to do the same experiment
d. copy your results several times and change the numbers a bit

3.it is important to conduct multiple trials because
a. that lets you control your experiment
b. it makes your results more convincing
c. scientists get paid for every trial that they complete
d. you will probably earn a better grade on the assignment

4.replication refers to
a. doing your own experiment again
b. other scientists doing your experiment
c. writing down a clear step-by-step procedure
d. sharing information between different scientists

5.what is one reason that writing clear step-by-step procedures is important?
a. it prevents you from faking results.
b. it makes repetition and replication easier.
c. it makes sure that no one copies your work.
d. it prevents anything from going wrong during the experiment.

6.in both repetition and replication,
a. other scientists are involved
b. an experiment is done again
c. scientists always get the same results
d. there is only a single experimental trial
7.the term validity refers to how
a. important a discovery is scientifically
b. clever the design of the experiment is
c. well-chosen the independent and dependent variables are
d. likely it is that other experiments will support the same conclusion

8.why is sharing information so important in science?
a. it allows you to repeat experiments.
b. it allows others to replicate experiments.
c. it allows scientists to stop anyone from faking results.
d. it allows multiple trials to be completed for your experiment.

9.repeating your experiment
a. increases validity
b. decreases validity
c. has no effect on validity

10.if you complete multiple trials of your experiment, that is called
a. repetition
b. restitution
c. replication
d. repudiation
