What is the key difference between replication and reproducibility?

Replication uses new data, while reproducibility uses the same data

What is one of the primary goals of replication in scientific research?

Confirming false positives (Type I errors)

Why is computational reproducibility important in statistical research?

It ensures that other researchers can verify results using the same data

Why does publication bias occur?

Journals prefer studies that confirm hypotheses

According to Karl Popper (1959), what is necessary for scientific observations to be tested?

They must be repeatable and follow regularities

What is the FAIR principle in open science?

Findable, Accessible, Interoperable, Reusable

What is a key advantage of Bayesian statistics over frequentist approaches?

It allows for incorporating prior beliefs into statistical inference

Why is there no such thing as an “exact replication” in scientific research?

Bc even if the same data & methods are used, small variations always exist

Questions 10

Answers

1
Which statistical approach incorporates prior beliefs into inferences?
Frequentist Statistics
Regression Analysis
Bayesian Statistics
Null Hypothesis Significance Testing (NHST)
2
which of the following is NOT a type of replication?
Statistical Replication
Direct Replication
Close Replication
Conceptual Replication
3
What is the key difference between replication and reproducibility?
Replication uses the same data, while reproducibility uses new data
Replication involves changing the methodology, reproducibility doesn't
There is no difference between replication and reproducibility
Replication uses new data, while reproducibility uses the same data
4
What is one of the primary goals of replication in scientific research?
Reducing sample size
Avoiding statistical modeling
Ensuring all studies reach statistical significance
Confirming false positives (Type I errors)
5
Why is computational reproducibility important in statistical research?
It allows researchers to change their hypothesis after data collection
It prevents researchers from needing to share their data
It reduces the need for statistical analysis
It ensures that other researchers can verify results using the same data
6
Why does publication bias occur?
Researchers have no interest in publishing positive results
Journals prefer studies that confirm hypotheses
Only replications are considered for publication
Negative results are often published more frequently
7
According to Karl Popper (1959), what is necessary for scientific observations to be tested?
They must be based on a single case study
They must be repeatable and follow regularities
They must always confirm the hypothesis
They must occur in a controlled laboratory environment
8
What is the FAIR principle in open science?
Formal, Accurate, Independent, Reliable
Frequentist, Adaptive, Informative, Robust
Findings, Accessibility, Interpretation, Reproducibility
Findable, Accessible, Interoperable, Reusable
9
What is a key advantage of Bayesian statistics over frequentist approaches?
It allows for incorporating prior beliefs into statistical inference
It is only used in experimental sciences
It eliminates the need for data collection
It does not require probability calculations
10
Why is there no such thing as an “exact replication” in scientific research?
Bc even if the same data & methods are used, small variations always exist
Because different researchers will always obtain the same results
Because replication always leads to new theories
Because replications are never conducted in science
