Child labor statistics are critical for assessing the extent and nature of child labor activities in developing countries. In practice, widespread variation exists in how child labor is measured. Questionnaire modules vary across countries and within countries over time along several dimensions, including...

In this talk, I use cases from biology and ecology to argue that meta-analysis has another, under-explored epistemic virtue. It allows scientists to better understand the causes and consequences of variation in a body of evid...
What is the modern science of heredity called? What is the Hardy-Weinberg principle? What determines an organism?s phenotype? What ensures genetic diversity in sex cells? What does the principle of biological inheritance state? Which processes lead to most genetic variation i...
Every reductionist has his favorite analogy from modern science. It is most unlikely that any of these unrelated examples of successful reduction will shed light on the relation of mind to brain. But philosophers share the general human weakness for explanations of what is incomprehensible in terms...
Variance: How the data is spread out. Standard deviation: Quantifies the amount of variation from the mean. Correlation: Measures the relationship between variables. Examples Statistics are drawn from populations, but a “population” doesn’t necessarily mean a physical count of bodies. It can ...
From the hoverboards of "Back to the Future" to the gravity guns of "Half-Life 2," science fiction is peppered with antigravity technology. In the real world of peer-reviewed studies, corporate-funded labs and general relativity, however, "antigravity" is a dirty word. Gravity, you undoubted...
Data preparation is done in a series of steps. There's some variation in the data preparation steps listed by different data professionals and software vendors, but the process typically involves the following tasks: 1. Data collection Relevant data is gathered from operational systems, data warehou...
(OOP), an instance is a specific realization of anyobject. An object may be different in several ways, and each realized variation of that object is an instance. The creation of a realized instance is calledinstantiation. In computing, an instance can take the form of a document type or ...
Psychometrics is a branch of data science. In fact, it’s been around a long time before that term was even a buzzword. Don’t believe me? Check out thisCoursera course on Data Science, and the first example they give as one of the foundational historical projects in data science is…...
