A point estimate is a single value (statistic) used to estimate a population value (parameter)true apex
perameter is a measure of population or universe, statistic is a measure of a sample data drawn from population
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.
Either.
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.
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.
A parameter describes a population. A statistic describes a sample.
A parameter is a numerical measurement of a population; a statistic is a numerical measurement of a sample.
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!)

© 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.
this is false... a parameter is a measure of a mean or mode, a measurable characteristic of a sample is called a statistic.
A larger random sample will always give a better estimate of a population parameter than a smaller random sample.
