For this reason, many scientists question the accuracy of published findings and now call for increased scrutiny of research practices in psychology.
Why is generalization and replication in research so important?
Why Is Replication so Important in Psychology? When studies are replicated and achieve the same or similar results as the original study, it gives greater validity to the findings. If a researcher can replicate a study’s results, it means that it is more likely that those results can be generalized to the larger population.
Why is replication important in scientific studies?
Why is replication important in science? 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 ...
Why is proofreading DNA in replication important?
Proofreading by DNA polymerase corrects errors during replication. Some errors are not corrected during replication, but are instead corrected after replication is completed; this type of repair is known as mismatch repair (Figure 2). The enzymes recognize the incorrectly added nucleotide and excise it; this is then replaced by the correct base.

What chapter is the importance of replication?
The importance of replication | in Chapter 01: Psychology and Science
Why is it important to replicate a phenomenon?
Replication is vital to science. It helps make science a self-correcting system. Any time a result is surprising, researchers will try to replicate it, to see if the phenomenon is dependable or just a fluke (a one-time occurrence).
Why is replication failure so common?
Most failures of replication are due to differences in how the research was performed. Possible differences include: the subjects involved (Nationality? Age? Volunteers or paid subjects?) the time of day, the weather, the expectations of the experimenter (a powerful effect), and many other variables.
Do research reports need to be replicated?
Students are taught that a research report should include all necessary details to permit replication. However, it is often impossible to find allrelevant details about how research is conducted in a published report of research.
Did the scientists try to replicate the experiment?
The reports of a successful transplant surprised other scientists. They tried to replicate the experiment, and they could not . In this case, after failed replications, the scientist confessed what he had done, so the mysterious results were explained.
What is Geo-Replication?
Geo-replication is a type of data storage replication. With geo-replication, the same business data is stored on servers in multiple locations. This helps provide redundancy, or a back-up, in case your data center fails or something unexpected happens that compromises the way that your data center functions. On a wide area network, or WAN, geo-replication can also help improve network performance as data is stored across geographically-distributed data networks, allowing users in different locations to access the same data at local-area network (LAN) speeds.
Why is it important to plan for unexpected events?
Though you may not want to think about, it is important to plan for unexpected events, especially when it comes to vital business data that you need in order to run your business successfully on a day-to-day basis.

Common Uses of Data Replication
- Improve the Availability of Data
Having data distributed across networks improves fault tolerance and accessibility, especially across global organizations. Data replication enhances the resilience and reliability of systems by storing data at multiple nodes across a global network. - Access Data for Reporting and Analytics
Data-driven organizations replicate data from multiple sources into data warehouses, where they use them to power business intelligence (BI) tools. Storing data from the various applications in a common data warehouse, also allows reports to span multiple applications. This gives BI users …
How Data Replication Works
- Replication involves copying data from a variety of source systems to different locations. For example, data can be copied between two on-premises hosts, between hosts in other locations, to multiple storage devices on the same host, or to or from a cloud-based host. Data replications can be done according to a schedule, in real-time, changed, or deleted in the master source. The chal…
Benefits of Data Replication
- By making data available on multiple hosts or data centers, data replication facilitates the large-scale sharing of data among systems and distributes the network load among multisite systems. Organizations can expect to see benefits including: 1. Improved reliability and availability: If one system goes down due to faulty hardware, malware attack, or another problem, the data can be …
Data Replication Methods
- First, let us examine the methods of data replication in the context of latency. Some use cases require real-time replication, such as having a standby database ready in the event of a database server failure.
Standby Databases
- Standby databases provide redundancy in the event of a database server failure. A corrupted filesystem or a broken network path can cause this to happen. In this case, a hot backup database that can be automatically switched to be the active database gives an extra layer of protection to keep systems running with no downtime. Several database platforms provide the ability to replic…
Near-Real Time Replication
- A fairly recent product space is near-real-time replication. This is used to create a data warehouse that is simply a clone of the source database. Instead of spending months designing and data mapping a data warehouse into a structure that simplifies the accessibility of information for reporting users, the source schema is recreated in the target warehouse database. This approac…
Data Replication Pitfalls to Avoid
- Data replication is a complex technical process. It provides advantages for decision-making, but the benefits may have a price.

What Is The Main Purpose of Replication Studies?
- The credibility of scientific studies is established only if it is replicable under similar or closely related conditions. Findings collected from such studies gives greater validity to the originally conducted research. Furthermore, it means that the original study is more likely to be generalized for larger applications and future research scope.
What Are The Types of Replication Studies?
- Replication studies are broadly classified as: 1. Exact or Direct replications– Direct replication is the repetition of an experimental procedure to the exact degree as possible. It means that exactly same equipment, material, stimuli, design and statistical analysis should be used. 2. Conceptual replications– Conceptual replication is when research is conducted by using differe…
An Unfair Reputation?
- A replication study attempts to validate the findings of a prior piece of research. By doing so, that prior research is confirmed as being both accurate and broadly applicable, since the replication study typically changes one or more variables of the original study, such as sample population, industry sector, etc. From the perspective of contributing to scientific research, replication studi…
The Challenges of A Replication Study
- Being able to replicate a simple study from a decade ago and observe how things may have changed over the last ten years, has saved the fortunes of more than one doctoral student struggling to find a research topic. However, replicating more recent research, especially projects making controversial claims, can prove to be extremely challenging. If the original research tea…
