Statistical Significance01:50

Statistical Significance

20.1K
Once data is collected from both the experimental and the control groups, a statistical analysis is conducted to find out if there are meaningful differences between the two groups. A statistical analysis determines how likely any difference found is due to chance (and thus not meaningful). In psychology, group differences are considered meaningful, or significant, if the odds that these differences occurred by chance alone are 5 percent or less. Stated another way, if we repeated this...

Longitudinal Research02:20

Longitudinal Research

11.8K
Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...

Cause and Effect01:53

Cause and Effect

10.9K
While variables are sometimes correlated because one does cause the other, it could also be that some other factor, a confounding variable, is actually causing the systematic movement in our variables of interest. For instance, as sales in ice cream increase, so does the overall rate of crime. Is it possible that indulging in your favorite flavor of ice cream could send you on a crime spree? Or, after committing crime do you think you might decide to treat yourself to a cone?

Hypothesis: Accept or Fail to Reject?01:17

Hypothesis: Accept or Fail to Reject?

27.5K
The outcome of any hypothesis testing leads to rejecting or not rejecting the null hypothesis. This decision is taken based on the analysis of the data, an appropriate test statistic, an appropriate confidence level, the critical values, and P-values. However, when the evidence suggests that the null hypothesis cannot be rejected, is it right to say, 'Accept' the null hypothesis?
There are two ways to indicate that the null hypothesis is not rejected. 'Accept' the null...

Types of Biopharmaceutical Studies: Controlled and Non-Controlled Approaches

115
Biopharmaceutical studies constitute a vital field aiming to enhance drug delivery methods and refine therapeutic approaches, drawing upon diverse interdisciplinary knowledge. In research methodologies, the choice between controlled and non-controlled studies significantly influences the study's reliability and accuracy.
Non-controlled studies, commonly employed for initial exploration, lack a control group, rendering them susceptible to biases and external influences. In contrast,...

Archival Research01:40

Archival Research

15.9K
Some researchers gain access to large amounts of data without interacting with a single research participant. Instead, they use existing records to answer various research questions. This type of research approach is known as archival research. Archival research relies on looking at past records or data sets to look for interesting patterns or relationships. For example, a researcher might access the academic records of all individuals who enrolled in college within the past ten years and...

Summary

The phrase "more research is needed" is often an empty conclusion in medical articles. Synthesizing existing and new knowledge can determine current understanding, saving resources when definitive answers are found.

Area of Science:

  • Medical research methodology
  • Knowledge synthesis
  • Scientific communication

Context:

  • The concluding phrase 'more research is needed' is prevalent in scientific literature.
  • This phrase often signifies a lack of definitive conclusions or a call for further investigation.
  • The current research landscape necessitates a critical evaluation of such concluding statements.

Purpose:

  • To critically analyze the utility and implications of the phrase 'more research is needed'.
  • To advocate for a more rigorous approach to synthesizing existing and new knowledge.
  • To propose that definitive conclusions can be reached, redirecting resources effectively.

Summary:

  • The common concluding phrase 'more research is needed' is argued to be an empty statement.
  • Synthesis of existing and newly acquired knowledge allows for a determination of the current state of understanding.
  • Research should only proceed if current knowledge is not definitive, optimizing resource allocation.

Impact:

  • Promotes a shift towards more conclusive scientific reporting.
  • Encourages efficient allocation of research funding and efforts.
  • Enhances the clarity and impact of scientific findings by avoiding redundant research calls.
