Yes. You could have a biased sample. Its distribution would not necessarily match the distribution of the parent population.

What is difference of population sample?
The population consists of every possible unit where a sample is a subset of the population. Note that population and sample need not refer to persons. For example, if studying biodiversity, the population could consist of plots of land.
Why is the sample mean an unbiased estimator of the population mean?
The sample mean is an unbiased estimator of the population mean because the average of all the possible sample means of size n is equal to the population mean.
What is usually not possible to compute one relies on a sample statistic?
Population Parameter
When the population standard deviation is not known the sampling distribution is a?
If the samples are drawn frm a normal population, when the population standard deviation is unknown and estimated by the sample standard deviation, the sampling distribution of the sample means follow a t-distribution.
What will happen if the sample you have drawn from the population does not represent the population?
You are studying the sample because you want to find out information about the whole population. If the sample you have drawn from the population does not represent the population, you will find out about the sample but will not find out about the population.

What proportion of sample proportions have a value greater than the population in any normal sample proportion distribution?
A half.

Population Parameter
What is subset of a population called?
A Sample
When the population standard deviation is not known the sampling distribution is a?
If the samples are drawn frm a normal population, when the population standard deviation is unknown and estimated by the sample standard deviation, the sampling distribution of the sample means follow a t-distribution.
What sentence is a true statement Is a sample a subset of the population or Is a population a subset of the sample?
A sample is a subset of the population.

You are studying the sample because you want to find out information about the whole population. If the sample you have drawn from the population does not represent the population, you will find out about the sample but will not find out about the population.
How is a sample related to a population?
A sample is a subset of the population.
How is a sample different from a population?
The sample is a subset of the population.
Sampling is a method of estimating population?
Sampling makes it possible to make assumptions about the larger population based on a small sample. This is beneficial in the study of population and demographics.
Is the data is sample or population?
Data is neither sample nor population. Data are collected for attributes. These can be for a sample or a population.
