Estimation

A new framework of data analysis where the new statistical methods are used for interpreting the results and analyzing the data is known as estimation in statistics.

Question

The main purpose of inferential statistics is to know whether:
random sampling error occurs.
the sample represents the population.
the sample is randomly selected.
the population size is larger than sample size.

Without the degrees of freedom, the standard deviation of population will be
estimated:
same
larger
randomly
smaller
