2.) </span>I<span>t is important to take a random sample of the population you want to study because the population may be too large that it might be impossible or too expensive to conduct a survey on a population.
3.) </span><span>An outlier is an observation point that is distant from other observations. It can be too small or too big compared to other observations.</span>
The measure of center that is more affected by outliers in the data is the mean, because since the mean is obtained by the sum of the data divided by the number of the data set. Any 'too big' number or 'too small' number will affect the sum of the data set.
