Basic Principles of Science

This video describes the qualities that distinguish scientific and non-scientific thinking.


The Fact-Value Distinction

Understanding the different between facts and values is essential to understanding the limits of science.


Testing Theories

How to differentiate stronger and weaker theories.


What is Measurement?

Measurement is a critical concern in the development of a social research project.


Types of Data to Collect in Social Research

A look at different types of information that one might collect in a social research project.


Validity

Validity concerns involve questions about whether our project’s measurements are capturing what they think they’re capturing.


Reliability

Reliability concerns involve questions about whether our measures deliver clear, consistent scores.


Measurement Error

Measurement error occurs when our measures are distorted.  A good research strategy seeks to control this kind of error.


Structure in Measurement

This video discusses the issue of structure in crafting a measurement strategy.




Logical Fallacies: Some Illustrative Examples

Fallacies are argumentative devices that give the appearance of having proven a point, even when no such proof has been delivered.
