\n" ); document.write( "Imagine you want to find the average height of everyone in the country. So the population is the set of people in this country.
\n" ); document.write( "The parameter would be the average height of everyone in that population. If you were to measure everyone in this population, then you are conducting a census, which tends to be very expensive (especially with large population sizes).\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The role of statistics is to gather a sample in which tries to estimate the population.
\n" ); document.write( "So for instance, if the population is 50% men and 50% women, then the sample of say 1000 people should have 500 men and 500 women.
\n" ); document.write( "When computing the sample mean, this is a sample statistic because the sample mean estimates the population mean. \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "In short, the entire class of statistics is aimed at estimating population parameters in which are too costly to obtain.
\n" ); document.write( "It doesn't have to be a monetary cost but also costs that pertain to natural resources or time.
\n" ); document.write( " \n" ); document.write( "
