Is the study of the collection, organization, analysis, interpretation, and presentation of data. The term is also used to represent the numerical characteristics of a sample (ex: the sample mean, variance…).

Develops the plot of the game as well as the characters and objects in the game and the settings that connect them into an emotional narrative that is gradually released as the game progresses.

A game that focuses on gameplay requiring careful and skillful thinking and planning in order to achieve victory. 

A variant on simple random and systematic sampling methods and is used when there is a number of distinct subgroups, within each it is required that there is full representation. A stratified sample is constructed by classifying the population in sub-populations (or strata), based on some well-known characteristics of the population, such as age, gender or socio-economic status. The selection of elements is then made separately from within each strata, usually by random or systematic sampling methods.

Significance test for assessing hypothesis about population means; a single sample t-test is used in situations where it is required to test whether the mean of a population takes a particular value; an independent samples t-test is designed to test the equality of the means of two populations, when independent samples  are available from each population.

Is a frequently used variant of simple random sampling. When performing systematic sampling, every element from the list is selected from a randomly selected starting point. For example, if we have a listed population of 6000 members and wish to draw a sample of 2000, we would select every 30th (6000 divided by 200) person from the list. In practice, we would randomly select a number between 1 and 30 to act as our starting point.
