Random sampling of quadrants is crucial to ensure that the collected data accurately represents the overall population or area being studied. This minimizes bias and allows for more reliable statistical inferences, as every part of the population has an equal chance of being included. Random samples help in capturing the variability within the population, leading to more robust and generalizable results. Ultimately, this enhances the validity of any conclusions drawn from the study.

Two random samples are dependent if each data value in one sample can be paired with a corresponding data value in the other sample.
A 'random' sample - covers all age groups, genders, and other criteria. A 'targeted' sample might only cover a small part of the population.
stratified sampling, in which the population is divided into classes, and random samples are taken from each class;cluster sampling, in which a unit of the sample is a group such as a household; andsystematic sampling, which refers to samples chosen by any system other than random selection.
fg
Data from random samples will not always include the same values. Values are chosen randomly and they may or may not be the same. So means will vary among random samples.

There are 25C7 different samples of seven from a pool of 25.25C7 = 25!/(7!(25-7)!) = 480 700 different samples of 7
