Alright, so here the question says that can you define three strategies which can be used to reduce the likelihood of committing statistical errors, right.
00:08
So in order to reduce the likelihood of committing statistical error, the first thing that we can do is then to choose an adequate sample size, right.
00:24
So one of the most common statistical error occurs, involves a sample that is either large or either too small which causes the unreliable results, right.
00:36
Now we need to ensure that the sample size is adequately large and we can do this by conducting a power analysis or by using statistical formulas in order to determine the required sample size on the basis of the desired effect size, level of significance and the statistical power, right.
00:55
So when we take a larger sample size, it usually enhances the precision and it reduces the margin of error.
01:03
Now the second thing is random sampling.
01:09
So statistical errors can also occur when the sample is not representative of the population that we are studying.
01:17
So one way to do, to reduce the chances of such error is by using random sampling methods which ensure that all the members of a population has an equal chance of being included in the sample which reduces the potential for any sort of bias, right...
