Sampling error is the difference between a population parameter and a sample statistic used to estimate it.
In statistics, a population is a set of similar items or events which is of interest for some question or experiment.
In statistics: Numerical measures. The range, the difference between the largest value and the smallest value, is the simplest measure of variability in the data. The range is determined by only the two extreme data values.
Measures of Central Tendency, In statistics, a central tendency is a central or typical value for a probability distribution. It may also be called a center or location of the distribution.
A measure of spread, sometimes also called a measure of dispersion, is used to describe the variability in a sample or population.
The standard error is a statistical term that measures the accuracy with which a sample distribution represents a population by using standard deviation.
A parameter, generally, is any characteristic that can help in defining or classifying a particular system.
Statistics is a form of mathematical analysis that uses quantified models, representations and synopses for a given set of experimental data or real-life studies. Statistics studies methodologies to gather, review, analyze and draw conclusions from data.
The mean (average) of a data set is found by adding all numbers in the data set and then dividing by the number of values in the set.
The median is the middle number in a sorted, ascending or descending, list of numbers and can be more descriptive of that data set than the average. ... If there is an odd amount of numbers, the median value is the number that is in the middle, with the same amount of numbers below and above.

In statistics, an outlier is a data point that differs significantly from other observations. An outlier may be due to variability in the measurement or it may indicate experimental error; the latter are sometimes excluded from the data set.
The standard deviation is a statistic that measures the dispersion of a dataset relative to its mean and is calculated as the square root of the variance. ... If the data points are further from the mean, there is a higher deviation within the data set; thus, the more spread out the data, the higher the standard deviation.
In statistics, correlation or dependence is any statistical relationship, whether causal or not, between two random variables or bivariate data. In the broadest sense correlation is any statistical association, though it commonly refers to the degree to which a pair of variables are linearly related.
