A Useful Statistical Technique for Replication Studies

Journal for Research in Mathematics Education, 1977
Eastman's (1975) recent expression in the JRME of concern over so few replication studies is a concern that should be shared by all who have an interest in research. Replication is critical in assessing the "significance" of research results. A correlation coefficient of .20, which is statistically significant at the .01 level, will be much more ...

Replicated measurements and algebraic statistics

2009
A basic application of algebraic statistics to design and analysis of experiments considers a design as a zero-dimensional variety and identifies it with the ideal of the variety. Then, a subset of a standard basis of the design ideal is used as support for identifiable regression models. Estimation of the model parameter is performed by standard least

A STATISTICAL ANALYSIS OF DIFFERENCE TESTS WITH REPLICATIONS

Journal of Sensory Studies, 1994
ABSTRACTThis paper proposes a statistical method for difference tests with repetitions. Classical methods for difference tests are based upon the binomial distribution, and are not concerned with the number of repetitions per judge. But when more than one replication of a difference test is required, judgements from different judges are more ...

Using Straggler Replication to Reduce Latency in Large-scale Parallel Computing

PERV, 2015
In cloud computing jobs consisting of many tasks run in parallel, the tasks on the slowest machines (straggling tasks) become the bottleneck in the completion of the job.

On Not Confusing the Tree of Trustworthy Statistics with the Greater Forest of Good Science: A Comment on Simmons et al.’s Perspective on Pre‐registration

Journal of Consumer Psychology, 2020
In this commentary on Simmons, Nelson, and Simonsohn (this issue), we examine their rationale for pre-registration within the broader perspective of what good science is.

What Psychology Teachers Should Know About Open Science and the New Statistics

, 2020
Psychology teachers have likely heard about the “replication crisis” and the “open science movement” in psychology, and they are probably aware that psychologists have proposed new standards for research practice.

Science with or without statistics: Discover-generalize-replicate? Discover-replicate-generalize?

Behavioral and Brain Sciences, 2022
AbstractOverstated generalizability (external validity) is common in research. It may coexist with inflation of the magnitude and statistical support for effects and dismissal of internal validity problems. Generalizability may be secured before attempting replication of proposed discoveries or replication may precede efforts to generalize.

Prediction of Success in Elementary Statistics: Three Replications [PDF]

Psychological Reports, 1976
Validity of 3 prognosis tests to predict success in elementary statistics was determined for 3 separate classes. The criterion was a composite test of 100 concepts, problems, and open-ended exercises. In all 3 classes, competence in algebra and in the ability to grasp and use meanings of newly defined symbols gave the optimum regression equations ...

Statistical Comparison of Original and Replicated Surfaces

2019
This article is focused on the statistical comparison of the original and replicated surface. Surface replication has been used for a long time, but recently a material with the commercial name Dentacryl™ has been used for the replication. However, this material has some disadvantages that outweigh the benefits.

Statistical Methods for Replicability Assessment

2022
The reproducibility of scientific discoveries is a hallmark of scientific research. Although its centrality is widely appreciated in the scientific community, precise definitions for reproducibility and quantitative approaches for replicability assessment are still lacking.
