ExperimentAn experiment is a procedure carried out to support or refute a hypothesis, or determine the efficacy or likelihood of something previously untried. Experiments provide insight into cause-and-effect by demonstrating what outcome occurs when a particular factor is manipulated. Experiments vary greatly in goal and scale but always rely on repeatable procedure and logical analysis of the results. There also exist natural experimental studies.
Self-efficacyIn psychology, self-efficacy is an individual's belief in their capacity to act in the ways necessary to reach specific goals. The concept was originally proposed by the psychologist Albert Bandura. Self-efficacy affects every area of human endeavor. By determining the beliefs a person holds regarding their power to affect situations, self-efficacy strongly influences both the power a person actually has to face challenges competently and the choices a person is most likely to make.
Twelfth gradeTwelfth grade (also known as 12th grade, grade 12, or senior year) is the twelfth year of formal or compulsory education. It is typically the final year of secondary school in most parts of the world. Students in twelfth grade are usually 17–18 years old. Some countries have a thirteenth grade, while other countries do not have a 12th grade/year at all. In Australia, the twelfth grade is referred to as Year 12. In New South Wales, students are usually 16 or 17 years old when they enter Year 12 and 17 or 18 years during graduation (end of year).
Computer scienceComputer science is the study of computation, information, and automation. Computer science spans theoretical disciplines (such as algorithms, theory of computation, and information theory) to applied disciplines (including the design and implementation of hardware and software). Though more often considered an academic discipline, computer science is closely related to computer programming. Algorithms and data structures are central to computer science.
Observational studyIn fields such as epidemiology, social sciences, psychology and statistics, an observational study draws inferences from a sample to a population where the independent variable is not under the control of the researcher because of ethical concerns or logistical constraints. One common observational study is about the possible effect of a treatment on subjects, where the assignment of subjects into a treated group versus a control group is outside the control of the investigator.
Large numbersLarge numbers are numbers significantly larger than those typically used in everyday life (for instance in simple counting or in monetary transactions), appearing frequently in fields such as mathematics, cosmology, cryptography, and statistical mechanics. They are typically large positive integers, or more generally, large positive real numbers, but may also be other numbers in other contexts. Googology is the study of nomenclature and properties of large numbers.
Names of large numbersTwo naming scales for large numbers have been used in English and other European languages since the early modern era: the long and short scales. Most English variants use the short scale today, but the long scale remains dominant in many non-English-speaking areas, including continental Europe and Spanish-speaking countries in Latin America. These naming procedures are based on taking the number n occurring in 103n+3 (short scale) or 106n (long scale) and concatenating Latin roots for its units, tens, and hundreds place, together with the suffix -illion.
Torah studyTorah study is the study of the Torah, Hebrew Bible, Talmud, responsa, rabbinic literature, and similar works, all of which are Judaism's religious texts. According to Rabbinic Judaism, the study is done for the purpose of the mitzvah ("commandment") of Torah study itself. This practice is present to an extent in all religious branches of Judaism, and is considered of paramount importance among religious Jews. Torah study has evolved over the generations, as lifestyles changed and also as new texts were written.
Eleventh gradeEleventh grade (also known as 11th Grade, Grade 11 or Junior year) is the eleventh year of formal or compulsory education. It is typically the third year of high school (and is the final year in some countries). Students in eleventh grade are usually 16-17 years of age. In Australia, Year 11 is the twelfth year of education and fifth year of high school education. Although there are slight variations between the states, most students in Year 11 are aged around fifteen, sixteen or seventeen.
Spearman's rank correlation coefficientIn statistics, Spearman's rank correlation coefficient or Spearman's ρ, named after Charles Spearman and often denoted by the Greek letter (rho) or as , is a nonparametric measure of rank correlation (statistical dependence between the rankings of two variables). It assesses how well the relationship between two variables can be described using a monotonic function. The Spearman correlation between two variables is equal to the Pearson correlation between the rank values of those two variables; while Pearson's correlation assesses linear relationships, Spearman's correlation assesses monotonic relationships (whether linear or not).
