A random sample in a poll refers to a subset of individuals selected from a larger population in such a way that every member has an equal chance of being chosen. This method helps ensure that the sample is representative of the overall population, reducing bias and improving the accuracy of the poll's results. Random sampling is crucial for generalizing findings and drawing valid conclusions from the data collected.
A random sample is a sample that is collected without any specific characteristics in mind. For instance, instead of collecting a sample of women or members of a particular age group, they are collected randomly off the streets.
The purpose of random sampling in a poll is to ensure that every individual in the population has an equal chance of being selected, which helps to create a representative sample. This minimizes bias and allows for more accurate generalizations about the entire population based on the sample's responses. By achieving a representative sample, the poll results are more reliable and reflective of the broader population's views.
A random sample is a sample drawn in such a way that every item in the population has an equal and independent chance of being included in the sample.In real life, the ability to choose a random sample is dependent on the type of object being sampled: If the population is small and in a single place, say balls in an urn, you just pick a ball out of the urn. But say you want to choose a random sample of the people in a small town. This is far more problematic - you have to have a list of all the people, and then choose random items from the list. But you may not have access to that list. Please see the story of the Literary Digest Presidential Election Poll at the related link to appreciate the problem of a non-random sample.
A random distribution is a random sample set displayed in the form of a bell curve. See random sample set.
to select a random sample you pick them at random
The election of 1948 demonstrated that a good poll needed a later sample.

Your question can not be answered as you give no "which is" to choose from.
the answer is Whether the sample was selected from the population by a random method
Random sampling ensures that a bias in the sampled subjects is avoided. It allows for a diverse and fairly chosen sample of the intended population.
