Replication means repetition of the treatments under investigation.An experimenter resorts to replication in order to average out the influence of chance factors on different experimental units.Thus repetition of treatments results in more reliable estimate than is possible with a single observation.
Precision of the experiment is directly proportional to the square root of replications.
Also the critical values of t decreases as degrees of freedom increases.
So increase in number of replications will result in increased accuracy since in that case even small differences will be detected.
So the statement is true.

True or False 1. If a study finds statistically significant association between exposure and disease, that must mean that every person who is exposed will get the disease. 2. A survey can be reliable but still not close to the true value. 3. Bias is random deviation of results from the truth. 4. Screening for disease is one type of secondary prevention. 5. In order for an infectious disease to occur, there must be a susceptible host.
