Values coding: codes that attempt to exhibit the inferred values, attitudes and beliefs of participants. In doing so, the research may discern patterns in world views. Sub-coding: Other names of this method are embedded coding, nested coding or joint coding. This involves assigning primary and second order codes to a word or phrase.
Based in grounded theory, open coding is the analytic process through which concepts (codes) are attached to observed data and phenomena during qualitative data analysis.It is one of the techniques described by Strauss (1987) and Strauss and Corbin (1990) for working with text.
Given an r-sample statistic, one can create an n-sample statistic by something similar to bootstrapping (taking the average of the statistic over all subsamples of size r). This procedure is known to have certain good properties and the result is a U-statistic. The sample mean and sample variance are of this form, for r = 1 and r = 2.
Educational research refers to the systematic collection and analysis of evidence and data related to the field of education. Research may involve a variety of methods [1] [2] [3] and various aspects of education including student learning, interaction, teaching methods, teacher training, and classroom dynamics.
The experience sampling method (ESM), [1] also referred to as a daily diary method, or ecological momentary assessment (EMA), is an intensive longitudinal research methodology that involves asking participants to report on their thoughts, feelings, behaviors, and/or environment on multiple occasions over time. [2]
They are also referred to as Internet research, [1] Internet science [2] or iScience, or Web-based methods. [3] Many of these online research methods are related to existing research methodologies but re-invent and re-imagine them in the light of new technologies and conditions associated with the internet. The field is relatively new and evolving.
The JN-25 code used in World War II used a codebook of 30,000 code groups superencrypted with 30,000 random additives. The book used in a book cipher or the book used in a running key cipher can be any book shared by sender and receiver and is different from a cryptographic codebook.
Quantitative psychological research findings result from mathematical modeling and statistical estimation or statistical inference. The two types of research differ in the methods employed, rather than the topics they focus on. There are three main types of psychological research: Correlational research; Descriptive research; Experimental research
