What else can I help you with?
Scientists do their experimental tests more than once so they can reduce the effects of chance errors.?
Yes? There is always a chance that experimental results happened by chance (something called a Type I error in Statistics which is bad, but over-emphasized). Replications (which are not done often enough) help protect us against such "accidental" effects because reproducing the results by chance is FAR less likely than just getting them once by chance. But reproducing REAL effects should be quite easy. Though if it is the same scientist, in the same lab, it is possible the results can be replicated even when they shouldn't be replicated, not by chance, but because of something systematic (dirty or faulty equipment, poor randomization, experimenter accidently communicates something to the participant, ...).

depent variables
Scientists do tests more than once to reduce chance of errors called conducting a what?
It is called repeated trials.
The choice of whether a particular organism belongs to the experimental group or the control group should be based on?
Chance
When enough experimental data support a hypothesis becomes a(an)?
The hypothesis can never really be proven correct; that's why scientists always say that they are 99.9% sure about things. If you drop a pencil, it will most likely always fall, but there is the slight chance that someday, it won't fall. Things in science always change.
What do the scientists do their experimental tests more than once so they can reduce the effects of chance errors this is called conducting?
Repeated Trials
What is called when scientists do their experimental tests more than once so they can reduce the effects of chance errors?

Scientists do their experimental test more than once so they can reduce the effects of chance errors This is called?
average result is the result when you do a few times of the same experiment and get a few result then you average it.

replicate
What scientific discovery made by chance as opposed to the scientific method?
Penicillin was discovered by chance in 1928 by Alexander Fleming when he noticed that a mold called Penicillium notatum killed bacteria in a culture plate. This accidental discovery led to the development of the first antibiotic and revolutionized medicine.
What is a tool that helps scientists determine if a phenomenon occurred by chance or if it is connected to an experimental variable?
Repetition of the experiment.
Assumption that experimental results are due to chance alone is called?
null
Scientists do tests more than once to reduce chance of errors called conducting a what?
It is called repeated trials.
Why is replication important in experimental?
Observed results are less likely to be affected by random chance.
