Repeated Trials
Scientists do their experimental tests ore than once, so they can reduce the effects of chance errors. this is called conducting _______________.
average result is the result when you do a few times of the same experiment and get a few result then you average it.

how can we reduce the harmful affects of gold mining
because exercises done in club reduces weight, it reduce mass, so club should be called mass watchers
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, ...).
