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!)
What else can I help you with?
Example of the difference between a parameter and a statistic?
perameter is a measure of population or universe, statistic is a measure of a sample data drawn from 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.

What is the difference between statistics and parameters?
Parameter is any attribute Statistic are the measured values of a parameter. A statistic is a sample value such as the average height of a group of students. A parameter is a functional constant such as the mean of a normal distribution. Statistics are often used to estimate parameters. For instance, a sample average is an estimate of the mean.
What is Confidence Intervals of Margin of Error?
The magnitude of difference between the statistic (point estimate) and the parameter (true state of nature), . This is estimated using the critical statistic and the standard error.
Does a parameter describe a population or a sample?
A parameter describes a population. A statistic describes a sample.
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
Difference between single parameter sensitivity and multiple parameter sensitivity?
Difference between single parameter sensitivity and multiple parameter sensitivity is that in multiple parameter sensitivity,defined parameters cannot be measured with a high degree of accuracy in the field or in the laboratory.
What is the difference between parameter and sample?
A parameter is an attribute that refers to the entire population. (For example, the mean price of all motor vehicles in a city). A sample is collected from this population of all motor vehicles in that city to compute a statistic (here, the statistic is the average price of the vehicles in the sample) which is representative of the true price.
What is the difference between parameter and statistics?
© The statistic describes a sample, whereas a parameter describes an entire population.© Example of statistic is, if we randomly poll voters in a particular election and determine that 55% of the population plans to vote for candidate A, then you have a statistic because we only asked a sample of the population who they are voting for, then we calculated what the population was likely to do based on the sample. Alternatively the example of parameter is, if we ask a class of third graders who likes vanilla ice cream, and 90% of them raise their hands, then we have a parameter because 90% of that class likes vanilla ice cream. We know this because you asked everyone in the population.© Statistic is a random variable. But parameter is constant, it is not a random variable.
Determine whether the given is a statistic or a parameter after taking the first exam 15 of the students dropped the class?
its a parameter
