It is a value calculated from the sample values only.It is a value calculated from the sample values only.It is a value calculated from the sample values only.It is a value calculated from the sample values only.
In a statistical context this is usually called a sample.
Add the values of the variable for all elements in the sample and divide by the number of elements on the sample.
The same basic formula is used to calculate the sample or population mean. The sample mean is x bar and the population mean is mu. Add all the values in the sample or population and divide by the number of data values.
There is no such thing. The standard error can be calculated for a sample of any size greater than 1.

A numerical value calculated for a sample is called a descriptive statistic.

A statistic is a value calculated from a data sample. For example, the mean (average) is a statistic. You calculate the mean by adding up the values of the data you have and dividing by the number of values. Usually, you want to know the corresponding value for the whole population but this is impossible to obtain in practice. So you have to use a statistic calculated from a sample. For eaxmple, if you want to know the height of sixteen year old students in the UK, you cannot measure every single student. So you measure a sample (selected randomly), and calculate the average height of the sample. This is a statistic. See: http://www.stats.gla.ac.uk/steps/glossary/basic_definitions.html#stat

If the sample is small or not randomly chosen, it may not have much meaning at all. If the random sample is large, it would generally be inferred that the distribution is symmetrical. The skewness of the data can be calculated.
INFERENCES Any calculated number from a sample from the population is called a 'statistic', such as the mean or the variance.
In general when you take a sample of values of a random variable you will find that those values lie around some central value that is characteristic of the total population for the random variable. A measure of central tendancy (such as a sample mean, sample mode or sample median) is a statistic which is intended to estimate the central value of the population using the values in the sample in some way.
