Which of the Following Is the Best Description of Our

Which of the following is the best description of our approach to statistics?

A) We calculate statistics to look for mathematical relationships between samples and
populations.
B) We perform mathematical operations with data values in order to compare the values in
samples to the values in populations.
C) We take samples from populations in order to calculate parameters, which we can then use
to predict the statistics of the population.
D) We want to know about a population but can't measure everything, so we use data from
a subset to infer what is probable for the population.
