Statistics is divided into two parts: Descriptive and Inferential Statistics. Suppose you have a column that contains N values. It can refer to the value of a statistic calculated from a sample of data, the value of a parameter for a hypothetical population, or to the equation that operationalizes how statistics or parameters lead to the effect size value. Statistical Treatment Of Data Thesis Formula Output – the results of the study which are presented in data matrix form. Statistical Entropy. The term called the expected value of some random variable X will be represented as E(X)= μx=∑. Every year the National Cancer Institute collects and publishes data based on patient demographics. If x is a random variable distributed as P(x), then (5) is the expected value of x. , x n, where each value is from a Gaussian distribution having the same mean µ but a different standard deviation i.

Statistical treatment of data greatly depends on the kind of experiment and the desired result from the experiment. For example, in a survey regarding the election of a Mayor, parameters like age, gender, occupation, etc. would be important in influencing the person's decision to vote for a particular candidate.
