What is replicability in scientific research?

Replicability means obtaining consistent results across studies aimed at answering the same scientific question using new data or other new computational methods. One typically expects reproducibility in computational results, but expectations about replicability are more nuanced.

What is replicability?

Replicability is obtaining consistent results across studies aimed at answering the same scientific question, each of which has obtained its own data. Two studies may be considered to have replicated if they obtain consistent results given the level of uncertainty inherent in the system under study.

What is the ideal replication rate of experiments in psychology?

c) The ideal replication rate should be between 50% and 100%.

What is the importance of replication in an experiment?

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.

What is replication in an experiment and why is it important quizlet?

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. Experimental units are the objects to which the treatments are applied.

Why is replication of a research study important quizlet?

replication is important because the results of a study can vary considerably depending on experimental conditions and the research method used.

What does it mean when you replicate a study quizlet?

What does it mean when you replicate a study? The same study is repeated, sometimes with a tiny variation. You just studied 70 terms!

What is epigenetics quizlet?

Epigenetics is the study of changes in individuals, and in individual cells, caused by changes in gene expression that are unrelated to changes in the genetic code itself (nucleotide changes) ● It’s a study of gene expression due to changes in chromatin structure resulting from the chemical modification of chromatin.

What is one benefit of a conceptual replication over a direct replication?

Numerous different ways of measuring helping behaviour have been used as well. In other words, even if nobody had ever tried to directly replicate the original research, the conceptual replications give us confidence that the underlying hypothesis – that a positive mood increases helping behaviour – is correct.

What is the difference between an exact and a conceptual replication?

There are different types of replication. Exact replications tell us whether the original findings are true, at least under the exact conditions tested. Conceptual replications help confirm whether the theoretical idea behind the findings is true, and under what conditions these findings will occur.

What is a conceptual replication?

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.

What is direct replication?

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).

What are the two types of replications?

The two types of replications are exact replications and conceptual replications. An attempt to replicate precisely the procedures of a study to see whether the same results are obtained.

What is direct replication in psychology?

Direct replication is the repetition of an experimental procedure to as exact a degree as possible. This means that, as far as possible, the same equipment, material, stimuli, design and statistical analysis should be used.

What does DNA replication produce?

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.

What enzymes are needed for DNA replication?

During DNA replication, one new strand (the leading strand) is made as a continuous piece. The other (the lagging strand) is made in small pieces. DNA replication requires other enzymes in addition to DNA polymerase, including DNA primase, DNA helicase, DNA ligase, and topoisomerase.

What are the 4 enzymes in DNA replication?

Enzymes involved in DNA replication are:

  • Helicase (unwinds the DNA double helix)
  • Gyrase (relieves the buildup of torque during unwinding)
  • Primase (lays down RNA primers)
  • DNA polymerase III (main DNA synthesis enzyme)
  • DNA polymerase I (replaces RNA primers with DNA)
  • Ligase (fills in the gaps)
