Learn the random sample definition and the simple random sample definition. Understand when and how to use a simple random sample in statistics...
between the two is that with a simple random sample, each object in the population has an equal chance of being chosen. With random sampling, each object does not necessarily have an equal chance of being chosen. Unequal probability sampling isn’t usually addressed in basic statistics courses....
In simple random sampling, researchers collect data from a random subset of a population to draw conclusions about the whole population.
Statistics - Simple random sampling - A simple random sample is defined as one in which each element of the population has an equal and independent chance of being selected. In case of a population with N units, the probability of choosing n sample units
Strictly, most inferential statistics quietly assume that our data are obtained by simple random sampling with replacement. A textbook example is drawing a marble from a vase, writing down its color and putting it back into the vase before sampling a second (third...) marble. Like so, each ...

sampling with replacement; bootstrap sampling; running simulations. A bag contains 8 poker chips, representing the outcome of an experiment. Each chip is like an observation. First, we demonstrate sampling with replacement by getting a random chip from the bag, writing down its value, and ...
An example of a simple random sample would be to choose the names of 25 employees out of a hat from a company of 250 employees. In this case thepopulationis all 250 employees, and the sample is random because each employee has an equal chance of being chosen. Random sampling is used in...
