¶ … experimental method, otherwise known as quantitative research or laboratory study, is to formulate a hypotheses, to collect the data, and test this hypotheses according to scientific principles that obstruct, as carefully as possible, bias, and then to analyze this data using statistical measures. The experimental method uses random sampling as part of its discourse.
Practical considerations usually limit the amount of control we have in structuring experiments, for instance we cannot always hope to randomize; we sometimes (more usually) often have to make do with the sample of participants given. This is when quasi-experimentation is employed.
This particular study is a quasi-experiment
Levels of measurement of the variables
There were two levels / conditions: (1) inquiry-based science curriculum and (ii) an inquiry-based science curriculum and reading strategy instruction
Types of statistics used to analyze the data and generate results
Three types of relevant psychological instruments were used to measure science literacy. An...
Understanding the Value of Qualitative Research Qualitative researchers have a number of different research strategies available to them, including case studies, phenomenology, grounded theory and ethnography. Each of these research strategies has its respective strengths and weaknesses, but ethnography in particular represents a special challenge since it seeks to learn more about a group of people from the perspective of an insider. The purpose of this paper is to provide a
This is yet another reason we cannot assume that data is 'objective' because it is quantitative in nature. For example, when constructing an experiment "an extreme groups design (e.g., assigning participants to high or low conditions) maximizes the variances of the components of the product term, it also results in much more power with respect to the interaction effect than would the corresponding observational design" (Cortina 2002: 343). Conversely,

The Question of Interest What type of research design should the researcher use? To answer the study's critical research
Self-Assessment The effective use of qualitative research When I first embarked upon this course, I only had a vague idea about the purposes of the different qualitative research methods. While I knew the distinctions between grounded theory, case studies, phenomenology, narratives, and ethnographies on an intellectual level, when I assessed different studies over the course of my own research, I was less concerned about the different processes used to reveal the results
The third position means stepping outside the situation and seeing issues from the point-of-view of a third party. NLP reminds us that people receive information in various sensory channels: the visual, the auditory, the kinaesthetic (perception of movement of effort) and the digital mathematical or reasoned thinking (Taylor, 2000). The idea being that people use all of these modes, but may have a preferred mode. Ethnographic approach: this takes its
International Banking Quantitative Study Introduction The purpose of this quantitative study is to assess the confidence levels of members of the international banking community with respect to the sector’s ability to weather another global economic crisis like that seen from 2007-2009 following the collapse of sub-prime in the U.S. and a tidal wave of leveraged defaults across the global banking sector which only found relief through central banking intervention (Haitsma, Unalmis &
