If the sample is not representative of the population, then the characteristics
of the sample are not the characteristics of the population.
Example:
If I want to estimate the percentage of the population that are men, and my
sample is the school's football team, my estimate would be that 100% of the
population is comprised of men. What went wrong with my survey ? Simple.
The football team is not a representative sample of the population, at least
not as regards gender.

Why is it important for a sample to be representative?
It is important for a sample to be representative, so that the whole population's view is counted, and not biased by one particular group within the population.
Why is it important to have a representative sample when doing surveys?
Because without representative sample, your results will not be valid.

When a sample is representative of a population is said to be what?
When a sample is representative of a population, it is said to be a "probability sample" or simply a "representative sample." This means that the characteristics of the sample accurately reflect those of the larger population, allowing for valid inferences and generalizations. Such samples are essential in statistical analysis to ensure the findings can be applied to the entire population.
What is a representative sample?
A sample that accurately reflects the characteristics of the population as a whole
Why is it important for a sample to be representative?
It is important for a sample to be representative, so that the whole population's view is counted, and not biased by one particular group within the population.
Which of these best describes why it is so important to have a representative sample?
To generalize results from the sample population to the target population.
Why is obtaining a representative sample important?
Many statistical statements for a population which are based on a sample are not valid if the sample is not representative.
Why is it important to have a representative sample when doing surveys?
Because without representative sample, your results will not be valid.
What is difference between sample and representative sample?
A sample is any subset of the total population. A representative sample is one that is chosen so that its characteristics are similar to that of the population.

What is relations between representative sample and population?
A representative sample is a randomly selected subset of the population.
What You decide you want your sample to be representative of the population. Which sampling process would provide the most representative sample?

If it has similar characteristics as the population the sample is termed?
It is called a representative sample.
How can you determine whether a sample is representative of a population?
Take a simple random sample.
