You asked: Which of the following types of replication can improve a study’s ecological validity?

How does replication increase validity?

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.

Which type of replication offers the best evidence for generalizability?

Successful replication provides evidence of generalizability across the conditions that inevitably differ from the original study; unsuccessful replication indicates that the reliability of the finding may be more constrained than recognized previously.

What are the three types of replication studies?

Virtual, operational, direct, and retest are terms used to indicate that a study is closely replicated. This strategies aproximate the original research design. Type 3. Systematic extension, constructive, systematic, and independent replications include the extension of an earlier study.

What is participant replication?

Participant Replication. Unlike other replications that deal with generalization across settings, participant replication is used in cases where there is reason to believe that an observed relationship found with on set of participants will not generalize to or will be different in another population of people.

Does replication increase external validity?

Replication is when a study can be done again and the same general results are found. … Replication is important for external validity because if a study can’t be replicated, how can we know that the results are true? If Asch’s results are found time and time again, then we can guess that they probably hold true.

What are the two types of replications?

At least two key types of replication exist: direct and conceptual. Conceptual replication generally refers to cases where researchers ‘tweak’ the methods of previous studies [43] and when successful, may be informative with regard to the boundaries and possible moderators of an effect.

What is a successful replication?


Specifically, a replication attempt is considered to be successful when both the original and replication study report a significant p-value, in addition to both studies having an effect in the same direction (e.g. [30,36]). This measure is known as ‘vote counting’ [30].

What does lack of generalizability mean?

Very simply, generalizability is a measure of how useful the results of a study are for a broader group of people or situations. … If the results can only be applied to a very narrow population or in a very specific situation, the results have poor generalizability.

Why are studies replicated?

It is very important that research can be replicated, because it means that other researchers can test the findings of the research. Replicability keeps researchers honest and can give readers confidence in research. … If the research is replicable, then any false conclusions can eventually be shown to be wrong.

What is low ecological validity?

Ecological validity refers to the ability to generalize study findings to real-world settings. … Low ecological validity means you cannot generalize your findings to real-life situations.

What are the different types of replication?

Types of data replication

  • Full table replication.
  • Transactional replication.
  • Snapshot replication.
  • Merge replication.
  • Key-based incremental replication.

What is an example of replication?

Replication is the act of reproducing or copying something, or is a copy of something. When an experiment is repeated and the results from the original are reproduced, this is an example of a replication of the original study. A copy of a Monet painting is an example of a replication.

What is clinical replication?

Clinical replication. refers to “the administration of a treatment package containing two or more distinct treatment procedures by the same investigator or group investigators….

What is systematic replication?

the process of conducting a study again but with certain consistent differences, often in an attempt to extend the original research to different settings or participants.

How do you determine if a study has been replicated?

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.
