A Numerical Measure from a Sample Such as a Sample Mean Is Known?
sample statistic
How do you measure the density of a material?
-- Get a piece of the material. It doesn't matter what size it is. -- Measure the mass of the sample. -- Measure the volume of the sample. -- Divide the mass by the volume. The result is the density of the material.
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 is a numerical value used as a summary measure for a sample called such as a sample mean?
sampl statistics
Is volume a measure of how much space a sample of matter takes up?
Yes. volume is a measure of how much space a sample of matter takes up!
What is a measure of the pull of gravity on a sample of matter?
gravity
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 does the test statistic measure?
The test statistic is a measure of how close the sample proportion is to the null value.
What is microcaliper?
It is a device that uses a pin and the pressure that it exerts on a surface of a sample to measure the sample's thickness (usually in units of micrometers). For example, if you wanted to find the thickness (in micrometers) of a sample of metal. You could place the mount/stand in the microcaliper and take the measurement. Then, measure the mount/stand with the sample. The difference between the two measurements will be the thickness of the sample.
What is the purpose of the blank?
Blank Sample in Spectrophotometry is used to measure the absorbance of light without sample. It is subtracted from the total absorbance for measurement of Absorbance from a sample's absorbance.
What is a ballot measure?
Counting votes for a sample of how an election is going.
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.
