Comparing and Contrasting Experimental and Correlational Research Designs
The two research methods are both quantitative research methods. Experimental research designs are mainly used to investigate causal relationships and studying relationships between one variable and another. Correlational research designs mainly try to establish if there is a relationship between two variables. Correlational research is nonexperimental because the researcher will be measuring two variables and assessing their statistical relationship. While experimental research will make use of independent and dependent variables, correlational research will not use any of these variables. In experimental research, the researcher can manipulate one of the variables, but for correlational research, no variable is manipulated but both variables are measured. The two research designs make use of hypothesis and the difference will come out based on whether the researcher assigned the participants to particular groupings or they just asked the participants the intended questions. In essence, correlational research does not perform any random assignment.
The selected article uses experimental research design and titled Motivated Recall in the Service of the Economic System: The Case of Anthropogenic Climate Change. The researchers indicate that people are more likely to recall climate change effects when there is an economic attachment associated with the information. The researchers conducted three different studies and in all the studies the experimental group demonstrated that they would be motivated by the economic system for them to recall evidence of climate change (Hennes, Ruisch, Feygina, Monteiro, & Jost, 2016). The researchers observed that people are not merely ignorant of this information, but rather they are motivated to justify their landscape of information in order to maintain their social status quo. Using the experimental research method, the researchers were able to randomly assign participants to different groups and share different information with the selected groups. This allowed the researchers to determine if there were any differences in the participant's responses.

Development Change Research Issue Developmental change is a broad topic that incorporate several sub-topics relating to an individual's growth and development. The broad nature of this topic emerges from the fact that its an approach that is geared towards explaining how infants, children, and adults change over a period of time. The process of explaining individuals' developmental changes over time involves examining a wide range of theoretical areas including biological, cognitive,
Construct a Research Design Using Secondary Data Part 1 Secondary data takes into account data that is gathered by someone else aside from the user. Examples of sources of secondary data comprise of data gathered by government establishments, organizational records in addition to data that was initially gathered for other purposes of research. The secondary data selected for this paper is census. In delineation, a census is the process of methodically obtaining
pilot study. The participants will be self-selected from among existing patients of a free clinic who meet specific criteria. The participants will be invited to attend a diabetes self-management course that is offered free of charge a local clinic. Once the self-selected individuals arrived at the clinic, there are additional selection criteria. The participants will be selected for having hemoglobin A1Cs greater than 10.0, for having Type 2 diabetes,
The Challenges of Dual Credit: A Research Proposal Problem Statements Dual credit or dual enrollment programs “are designed to boost college access and degree attainment, especially for students typically underrepresented in higher education,” (United States Department of Education, 2017, p. 1). With this lofty goal set, it should seem that dual credit programs would be reducing the educational achievement gap. After all, dual credit programs by definition allow all students the opportunity
Research Methods Literature Review A literature review on an identified research topic or issue is an important element when conducting a study regardless of whether the study employs qualitative, quantitative or mixed methods research design. The significance of conducting a literature review is attributable to the several functions and roles the review plays in the research process. Literature review is crucial when conducting a study because it’s a means of synthesizing
