With a probabilistic method, each member of the population has the same probability of being selected for the sample. Equivalently, given a sample size, every sample of that size has the same probability of being the sample which is selected. With such a sample it is easier to find an unbiased estimate of common statistical measures. None of this is true for non-probabilistic sampling.
What is the difference between quota sampling and cluster sampling
Sampling error leads to random error. Sampling bias leads to systematic error.

Sampling bias.
Random sampling is picking a subject at random. Systematic sampling is using a pattern to pick subjects, I.e. picking every third person.
Oh, dude, it's like asking the difference between a taco and a burrito - they're both delicious, but they have their own unique flavors. Stochastic is more about randomness and unpredictability, while probabilistic is all about calculating probabilities and likelihoods. So, like, stochastic is the wild card at the party, and probabilistic is the one crunching numbers in the corner.
Probabilistic epigenesis is a theory that suggests development occurs through bidirectional interactions between genetic and environmental influences. It posits that both nature (genetics) and nurture (environment) play a role in shaping an individual's growth and development, with outcomes being probabilistic rather than determined solely by genes or environment alone. This theory highlights the complexity of development and the significance of interactions between genetic predispositions and environmental factors.

a
Simple!
sample is a noun and sampling is TO sample(verb)
The difference between convenience and incidental sampling is that convenience sampling chooses the easiest people to reach when a sampling is done, whereas incidental sampling is done at random.
Sampling error leads to random error. Sampling bias leads to systematic error.
Pesistentent CSMA sense the channel continuously where as non pesistent CSMA resense the channel after a time decided randomly or based on probabilistic work----- Sanjay Bhaumick

the difference is just that non-probability sampling does not involve random selection, but probability sampling does.
The main difference between the quota and stratified sampling is that in the stratified sampling the researcher can not select the individuals to be included in the sample (he doesn't have control over who will be in the simple), but in the quota sampling the researcher has control over who will be in the sample (he can contact certain people and include them in the sample).
