Correlation does not Imply Causality, but then again… (7-4)
Correlation Does Not Imply Causation. When we see a correlation, we should not assume a cause-and-effect relationship between the variables. Correlation does not mean one isn’t causing the other, either; we just need more information. The correlation between two variables may be caused by

RELATIONSHIPS Between Variables: Standardized Covariance (7-1)
Correlation is a way of measuring the extent to which two variables are related. The term correlation is synonymous with “relationship.” Variables are related when changes in one variable are consistently associated with changes in another variable. Dr. Daniel reviews Variance, Covariance,

Four Uses of Correlation in Statistics (13-3)
Correlation is fundamentally about understanding the direction and strength of the relationship between variables, but it can also do a number of other useful jobs. • Correlation can test for reliability, such as test-retest reliability or Cronbach’s alpha. • Correlation can test for val

A Gentle Introduction to Correlation – Relationships Between Variables (13-1)
The topic of correlation is one of the most enjoyable parts of statistics, because everyone can understand correlation. We all know what it is to have relationships with other people and we know how our behavior can change when we are around others. Except that instead of relationships bet

Foundational Correlation – The Correlation Coefficient (13-5)
The correlational coefficient measures how closely the data fit the model of a straight line on a scatterplot diagram. The concept of correlation was invented by Sir Frances Galton and developed by statistician Karl Pearson. Linear correlation means that the correlation can be graphed in a
