Statistics is the science of making effective use of numerical data relating to groups of individuals or experiments. A poll is a good example of the use of statistics. Take… for example company X wants too find out what majority uses their products the most, so they poll several groups, which depending on the company may be, age, ethnic background, etc. Say they poll groups A, B, C, & D. Let's say they receive the following information that the percentage of persons in each group uses their products. Group A 75% Group B 45% Group C 95% Group D 25% Now company X can proceed to decide how to better their product, perhaps they choose to focus on Group D and figure out a way to attract more business from that group while still keeping their strongest groups A & C satisfied. There are a number of definitions of statistics.There is one definition that relates to the field of statistics, as:A collection of methods for planning experiments, obtaining data and then organizing, summarizing, presenting, analyzing, interpreting and drawing conclusions based on data. (Ref 1)There is a second definition, statistics is the plural of statistic, where statistic is defined as:A statistic is a numerical measurement describing some characteristic of a sample. (Ref 1)Finally, a third definition, that can be called the "mathematical or conceptual statistic", used by mathematicians and others to develop equations.If X 1 , X 2, ... X n is a random sample of a random variable, then the sample are elements of the random variable. A statistic is any function of the elements of a random sample. (Ref 2)I would add when the word "statistics" is used, most of the time they are referring to data related statistics (definitions 1 and 2) and not mathematical statistics.References:1. Elementary Statistics by Triola (2003).2. Introduction to Probability Theory and Statistical Inference, by Larson (1974).
The definition of statistics is the science of conducting studies to collect, organize, summarize, analyze and draw conclusions from data.

The number of samples, or sample size, is the number of measurements performed for a particular statistic. For instance, if you were trying to calculate the average price for …a bottle of Ardbeg 10 year old Scotch whisky, the number of samples would be the total number of prices you found for Ardbeg at various liquor stores. To continue on with this example, to get the average price, you would then add up all of the prices you measured and then divide that by the number of samples, as described above. It should be obvious that the more stores you visit to measure the price, in this case meaning the higher number of samples you obtain, the more accurate your value for the average price will be.
Website statistics let you know how many hits you're getting on your website. It helps to allow you to figure out what is driving traffic to your site and what is not.
