Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
If you choose a sample of the population that gives each person an equal chance of participating, this would be:
A
A biased sample
B
A random sample
C
An optimal sample
D
An atypical sample
Explanation: 

Detailed explanation-1: -Simple random sampling is a type of probability sampling in which the researcher randomly selects a subset of participants from a population. Each member of the population has an equal chance of being selected. Data is then collected from as large a percentage as possible of this random subset.

Detailed explanation-2: -Simple random sampling. In simple random sampling (SRS), each sampling unit of a population has an equal chance of being included in the sample. Consequently, each possible sample also has an equal chance of being selected. To select a simple random sample, you need to list all of the units in the survey population.

Detailed explanation-3: -Definition: Random sampling is a part of the sampling technique in which each sample has an equal probability of being chosen. A sample chosen randomly is meant to be an unbiased representation of the total population.

Detailed explanation-4: -One of the key advantages of probability sampling is that it is the easiest to measure for error. Probability sampling methods include: Random sampling is the truest form of probability sampling. This type of sampling guarantees that each member of a population has an equal chance of being included in the sample.

Detailed explanation-5: -Simple random sampling is the basic sampling technique where we select a group of subjects (a sample) for study from a larger group (a population). Each individual is chosen entirely by chance and each member of the population has an equal chance of being included in the sample.
