When are two random samples dependent?
Two random samples are dependent if each data value in one sample can be paired with a corresponding data value in the other sample.
Why are random samples more representative of the population than other kinds of samples?
A 'random' sample - covers all age groups, genders, and other criteria. A 'targeted' sample might only cover a small part of the population.
Different types of random and non random sampling?
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.
How many different simple random samples of 7 are possible from a pool of 25?
There are 25C7 different samples of seven from a pool of 25.25C7 = 25!/(7!(25-7)!) = 480 700 different samples of 7

Why don't psychologists use random samples often?
Psychologists may not always use random samples due to practical constraints such as time, resources, and accessibility to diverse populations. They may also prioritize other sampling methods like convenience or snowball sampling based on their specific research questions and goals. Additionally, some research designs may not require random samples as long as they adequately represent the population of interest.
