Why is replication important to psychology as a science?
Replication is vital to psychology because studying human behavior is messy. There are numerous extraneous variables that can result in bias if researchers are not vigilant. Replication helps verify that the presence of a behavior at one point in time is not due to chance.
Replication of studies using experimental methods is important because it helps check the validity of knowledge from previous research and enables questions concerning generalization across populations or contexts to be discussed.
replication means that each treatment is used more than once in an experiment. Important because it allows us to estimate the inherent variability in the data. This allows us to judge whether an observed difference could be due to chance variation.
What is the role of replication in psychological research? Replication reduces the chances that findings are due to experimenter bias, methodological flaws, or sampling errors. Cynthia wants to ensure that her research is consistent with the scientific method.
- Replication gives a study credibility, and it is a crucial part of the scientific process. When a researcher performs a study again, it is known as a replication study. - Even when the original investigation has a statistically significant result, researchers still have to conduct a replication study.
DNA replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. Replication is an essential process because, whenever a cell divides, the two new daughter cells must contain the same genetic information, or DNA, as the parent cell.

Replication studies guard against the destructive consequences of p-hacking. What is replication? scientist attempts to exactly recreate the scientific methods used in conditions of an earlier study to determine whether the results come out the same.
A replication study in which researchers repeat the original study as closely as possible to see whether the original effect shows up in the newly collected data. Also called exact replication. See also conceptual replication, replication-plus-extension. ecological validity.
Replication reduces variability in experimental results, increasing their significance and the confidence level with which a researcher can draw conclusions about an experimental factor.

What does replication mean in psychology?
n. the repetition of an original experiment or research study to verify or bolster confidence in its results.
Replication. Occurs when each treatment is applied to more than one experimental unit; ensures the effect of a treatment is not due to some characteristic of a single experimental unit. Completely randomized design. One in which each experimental unit is randomly assigned to a treatment.
Why are so many psychologists concerned about the replicability of their research? Apparently significant results can occur by accident.
the process in which one DNA molecule produces two identical DNA molecules, occurs before the cell divides.
The most direct method to assess replicability is to perform a study following the original methods of a previous study and to compare the new results to the original ones.
DNA replication occurs in all living organisms acting as the most essential part for biological inheritance. This is essential for cell division during growth and repair of damaged tissues, while it also ensures that each of the new cells receives its own copy of the DNA.
Replicability and replication are very important to the process of ensuring the validity of scientific findings. Pure replications can verify that a past analysis was done correctly and statistical replications provide some sense that a study's (or aggregated studies') findings are valid.
A replication study is a study that is an independent repetition of an earlier, published study, using sufficiently similar methods (along the appropriate dimensions) and conducted under sufficiently similar circumstances.
The replication crisis or replicability crisis or reproducibility crisis is an ongoing (2019) methodological crisis in which it has been found that many scientific studies are difficult or impossible to replicate or reproduce. The replication crisis affects the social and life sciences most severely.
There are two types of replications to consider: exact replications and conceptual replications.
Which of the following types of replication investigates the same research question as a previous study but uses different procedures quizlet?
This is why we have other types of replication... CONCEPTUAL REPLICATION: researchers explore the same research question but use different procedures. Conceptual variables in the study are the same, but the procedures for operationalizing the variables are different.
In many cases, non-replicated research is caused by differences in the participants or in other extraneous variables that might influence the results of an experiment.
Conceptual replication means that researchers re-test the same theoretical idea or hypothesis repeatedly, but use different populations, different ways of manipulating variables, different ways of measuring variables, or using different study designs.
A replication study involves repeating a study using the same methods but with different subjects and experimenters.
- If a node stops working, the distributed network will still work fine due to its replicas which will be there. ...
- It also helps in load sharing where loads on a server are shared among different replicas.
- It enhances the availability of the data.
How To Think About Replication (LE: Module 2, Part 6) - YouTube
Scientists aim for their studies to be replicable — meaning that another researcher could perform a similar investigation and obtain the same basic results. When a study cannot be replicated, it suggests that our current understanding of the study system or our methods of testing are insufficient.
DNA replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. Replication is an essential process because, whenever a cell divides, the two new daughter cells must contain the same genetic information, or DNA, as the parent cell.
Replication is a study for which any outcome would be considered diagnostic evidence about a claim from prior research. This definition reduces emphasis on operational characteristics of the study and increases emphasis on the interpretation of possible outcomes.
In science, replication is the process of repeating research to determine the extent to which findings generalize across time and across situations. Recently, the science of psychology has come under criticism because a number of research findings do not replicate.
What is the importance of DNA replication?
Cells must replicate their DNA before they can divide. This ensures that each daughter cell gets a copy of the genome, and therefore, successful inheritance of genetic traits. DNA replication is an essential process and the basic mechanism is conserved in all organisms.
Replication. Occurs when each treatment is applied to more than one experimental unit; ensures the effect of a treatment is not due to some characteristic of a single experimental unit. Completely randomized design. One in which each experimental unit is randomly assigned to a treatment.
Replication involves writing or copying the same data to different locations. For example, data can be copied between two on-premises hosts, between hosts in different locations, to multiple storage devices on the same host, or to or from a cloud-based host.
The “replication crisis” in psychology, as it is often called, started around 2010, when a paper using completely accepted experimental methods was published purporting to find evidence that people were capable of perceiving the future, which is impossible.
If research results can be replicated, it means they are more likely to be correct. Replication is important in science so scientists can “check their work.” The result of an investigation is not likely to be well accepted unless the investigation is repeated many times and the same result is always obtained.
Direct replication is defined as attempting to reproduce a previously observed result with a procedure that provides no a priori reason to expect a different outcome (Open Science Collaboration, 2015; Schmidt, 2009).
The cell cycle will not proceed to the next stage. Due to which the subsequent division will not happen. This will lead to cell death.
DNA replication plays a role in maintaining the genetic continuity of species because it makes a perfect copy of DNA for new cells.
The main role of DNA is to carry genetic information and dictate the process of protein synthesis. DNA provides the set of instructions to direct the cell to produce proteins vital for cell function.
