Is a single number characteristic describe a population is called a parameter?
Parameter
What sample statistic is used to estimate a population parameter?
A point estimate is a single value (statistic) used to estimate a population value (parameter)true apex
The characteristic or value of a population that is under consideration is called?
Population Parameter
What is used to estimate the population parameter?
point estimate
What is the difference between population and parameters?
The population is a group of interest, such as the people who filled out a recent survey about their age. The parameter is the descriptive measure of that population. So in this example, a parameter could be the average age of the people who filled out the survey.
Does a parameter describe a population or a sample?
A parameter describes a population. A statistic describes a sample.
Does a parameter ever change for a set population?
No, a parameter is a fixed value that describes a characteristic of a population. It does not change for a set population. Parameters are typically determined by conducting a study or analysis of the population.

What is the significance of the phi-hat symbol in statistical analysis?
The phi-hat symbol in statistical analysis represents the sample estimate of the population parameter phi. It is important because it helps researchers make inferences about the population based on the data collected from a sample.
A numerical summary of a population is a?
Parameter
Does the confidence interval always contain the true population parameter?
No, the confidence interval (CI) doesn't always contain the true population parameter. A 95% CI means that there is a 95% probability that the population parameter falls within the specified CI.
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.
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!)
