Does a parameter describe a population or a sample?
A parameter describes a population. A statistic describes a sample.
How does a parameter and a statistic differ?
A parameter is a numerical measurement of a population; a statistic is a numerical measurement of a sample.
Is a sample a number describing some characteristic of a statistic?
No. A statistic is a number describing a characteristic of a sample.
What is the the relationship between population and sample parameter and statistic?
The relations depend on what measures. The sample mean is an unbiased estimate for the population mean, with maximum likelihood. The sample maximum is a lower bound for the population maximum.
What is the difference between a parameter and a statistic?
A parameter is a number describing something about a whole population. eg population mean or mode. A statistic is something that describes a sample (eg sample mean)and is used as an estimator for a population parameter. (because samples should represent populations!)
Is The average annual salary for 35 of a companys 1200 accountants is 57000. This describes a parameter?
No, this description does not represent a parameter; it refers to a statistic. A parameter is a value that describes a characteristic of an entire population, while a statistic describes a characteristic of a sample. In this case, the average salary of $57,000 pertains to a sample of 35 accountants out of the total population of 1,200 accountants in the company.
Does a parameter describe a population or a sample?
A parameter describes a population. A statistic describes a sample.
What word means any measurable characteristic?
You could describe any measurable characteristic as a trait.
Is a single number characteristic describe a population is called a parameter?
Parameter
The characteristic or value of a population that is under consideration is called a population?
The characteristic or value of a population that is under consideration is called a parameter. It represents a specific aspect of the entire population and is often unknown and estimated using sample data. Parameters can include means, proportions, variances, and other measures that describe the population.
How does a parameter and a statistic differ?
A parameter is a numerical measurement of a population; a statistic is a numerical measurement of a sample.
Does each sample have measurable mass?
Yes, each sample has a measurable mass, which can be determined using a balance or scale. The mass is an important property that can provide information about the quantity of material present in the sample.
What is the value of a variable for an entire population that usually cannot be found directly?
The value of a variable for an entire population that cannot be found directly is known as a "population parameter." It represents a specific characteristic, such as the mean or proportion, of the entire population. Since it's often impractical or impossible to measure every individual in a population, researchers typically estimate this parameter using sample data. These estimates are referred to as "sample statistics," which serve as approximations of the population parameter.
A physical property is a characteristic of a substance is one that?
Density is a physical property; physical properties are measurable.
What is the difference a parameter and a statistic?
A parameter is a number describing something about a whole population. eg population mean or mode. A statistic is something that describes a sample (eg sample mean)and is used as an estimator for a population parameter. (because samples should represent populations!)
Is a sample a number describing some characteristic of a statistic?
No. A statistic is a number describing a characteristic of a sample.
What is the the relationship between population and sample parameter and statistic?
The relations depend on what measures. The sample mean is an unbiased estimate for the population mean, with maximum likelihood. The sample maximum is a lower bound for the population maximum.
