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!)
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.

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 relationship between sample and population?
From a sample of a population, the properties of the population can be inferred.
