All of the following below are possible sources of error in a scientific investigation except for a.using the wrong equipment du
ring the experiment b.discovering new variables as the experiment proceeds. c.completing multiple trials during an experiment. d. Not controlling all the variables in an experiment
The answer is C
Completing multiple trials during an experiment
The rest of the options are possibilities of how you can "mess up" and experiment, but if you run multiple trials doing everything right, for example, making sure all variables are controlled, using the right equipment, and making sure you cover all possible variables. If you make sure you do multiple trials and you do them right, you get successful results.
So the answer is C
I hope this was helpful :)
Goodluck!!
Answer: c. completing multiple trials during an experiment.
An error is mistake or inaccurate result obtained after accomplishment of scientific protocol. Completing multiple trials during an experiment can be a method to remove error from the experiment. A concordant reading in three or more trials can be a conclusive result instead of one attempt.
