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.

Will a sample descriptive statistics accurately estimate the underlying population's parameters?
The alternativehypothesis (Ha or H1) describes the population parameters that the sample data represent, if the predicted relationship exists. It is always the hypothesis of difference. That is as opposed to the null hypothesis (H0) that describes the population parameters that the sample data represent if the predicted relationship does not exist. See Basic Statistics of the Behavioral Sciences by Heiman.
Greek letters are used for population parameters. Eg: µ is the population mean English letters are used for sample statistics. Eg: x-bar is the sample mean
Asymmetric is the opposite of symmetric
It is the difference between the highest and lowest value in a set of data.
