A numerical value used as a summary measure for a sample such as sample mean is known as a?
This is called a sample statistic. They are often used to give a general picture of a more specific whole.
Which measure of central tendency can be used for both numerical and categorical variables?
mean
What measure of central tendency is most stable from sample to sample?
Statistically speaking, the mean is the most stable from sample to sample. Whereas, the mode is the least stable statistically speaking from sample to sample.
What does it mean to say that the sample variance provides an unbiased estimate of the population variance?
It means you can take a measure of the variance of the sample and expect that result to be consistent for the entire population, and the sample is a valid representation for/of the population and does not influence that measure of the population.
What is the difference between calculating the sample mean and the population mean?
You calculate the actual sample mean, and from that number, you then estimate the probable mean (or the range) of the population from which that sample was drawn.

What is a numerical value used as a summary measure for a sample called such as a sample mean?
sampl statistics
Know as the measure of sample?
Mean or average is the most common measure of central tendency of a sample.
Which measure of central tendency can be used for both numerical and categorical variables?
mean
What does the standard error mean?
For a sample of data it is a measure of the spread of the observations about their mean value.
What is the single quantity compared to an entire sample?
The single quantity compared to an entire sample is called a statistic. It is a numerical measurement calculated from the data in the sample, such as the mean, median, or standard deviation. The statistic provides insight into the characteristics or properties of the sample as a whole.
What measure of central tendency is most stable from sample to sample?
Statistically speaking, the mean is the most stable from sample to sample. Whereas, the mode is the least stable statistically speaking from sample to sample.
Which numerical measure of center is most affected by extremely high or low numeric data?
Mean.
Is a parameter a measurable characteristic of a sample?
this is false... a parameter is a measure of a mean or mode, a measurable characteristic of a sample is called a statistic.
What is the difference between the sample mean and the population mean known as?
Sampling bias.
What does it mean to say that the sample variance provides an unbiased estimate of the population variance?
It means you can take a measure of the variance of the sample and expect that result to be consistent for the entire population, and the sample is a valid representation for/of the population and does not influence that measure of the population.
What is quantity mean in math?
a value or component that may be expressed in numbers.
