Max-min-con principle in the context of research methodology denotes:

Correct option is B

Maximizing systematic variance, minimizing error variance, controlling extraneous variance
Explanation of the Correct Answer: The Max-Min-Con principle in research methodology refers to:
● Maximizing systematic variance: Enhance the differences between experimental conditions to detect true effects
● Minimizing error variance: Reduce random error and measurement error to improve precision
● Controlling extraneous variance: Control for confounding variables that might affect the dependent variable
This principle helps researchers design studies that can detect true effects while minimizing threats to internal validity.

Information Booster: Key Points about Max-Min-Con Principle

• Systematic Variance: The variance of interest that we want to study - the effect of our independent variable
• Error Variance: Random fluctuations in measurements that reduce our ability to detect true effects
• Extraneous Variance: Variance caused by variables other than our independent variable that could confound results
• Statistical Power: Following this principle increases statistical power to detect true effects
• Experimental Design: Guides decisions about randomization, control groups, and measurement procedures
• Validity Enhancement: Improves both internal validity (by controlling extraneous variables) and statistical conclusion validity
