Abstract:
This paper briefly recounts the details of one of the first studies of whole brain, single subject variability in functional Magnetic Resonance Imaging (fMRI). In this paper I will not attempt to provide an overview of fMRI reliability, but will instead revisit the choices we made in performing our experiment as we did.

01:29Reliability and Validity
Reliability and validity are two important considerations that must be made with any type of data collection. Reliability refers to the ability to consistently produce a given result. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways.
01:11Variability: Analysis
Measures of variability are statistical metrics that reveal the dispersion pattern within a dataset. They are pivotal in biostatistics, providing insights into the heterogeneity within health and biological data. Variability signifies the degree to which data points diverge from one another, helping researchers understand the potential range of values and associated uncertainty within the data.
The range is a simple measure of variability, indicating the difference between the highest and...
