Question 1

Which of the following examples
demonstrates replication?
1 pts
O Addison is conducting an experiment using
water. She has a friend look over the
procedures before completing 30 trials.
O Rashawn is conducting an experiment using
tennis balls. He completes 30 trials and has 2
of his friends complete the experiment by
following the his procedures.
O Amanda is conducting an experiment using
aluminum foil. She completes her experiment 1
time and makes adjustments to her procedures.
She then completes 20 trials of her experiment.
O Joseph conducts his own experiment 25 times.

Answer 1

i’d say it’s the second one

“Rashawn is conducting an experiment using tennis balls. He completes 30 trials and has 2 of his friends complete the experiment by following his procedure”

explanation: the question asks for replication, not repetition.

replication is when, for example, you do an experiment and your friend does the exact same thing, like Rashawn’s situation

all the other options demonstrate repetition, which is basically doing trials (when the same person does the same experiment multiple times)

hope this helps :)
