Data democratization is the process of making digital information accessible to the average non-technical user of information systems without requiring IT involvement. It is the foundation for self-service analytics, an approach that allows these less-than-technical users (i.e., line-of-business) ...
If one of your variables has an artificially restricted range, then the correlation will be pushed closer to zero. The correlation between 1m inute and 5 minute APGAR scores is 0.66. If we restrict the data set to babies with one minute APGAR > 5, then the correlation declines to 0.25. ...
When you have more than two variables, you can arrange the correlations between every pair into a matrix. At the bottom of this page is an example using the blood viscosity data. To create this table, selectANALYZE | CORRELATE |BIVARIATE from the SPSS menu. ...
Correlation vs. causation: Just because two variables are associated doesn't mean they're necessarily related or dependent on one another. Confirmation bias: This occurs when you interpret data in a way that confirms your own preconceived notions. To avoid this, have multiple people interpret the...

Correlation is the degree to which the prices of assets move together. If the prices move in a similar proportion and in the same direction, they have a high correlation. If they move in opposite directions, they have a high negative correlation.
Data analytics as a practice is focused on using tools and techniques to explore and analyze data in real-time or near-real-time to uncover hidden patterns, correlations, and trends. The goal is predictive and prescriptive analysis, using advanced techniques to make accurate, dynamic, and forwar...
There are several methods of calculating correlation. The most common method, the Pearson product-moment correlation, is discussed further in this article. The Pearson product-moment correlation measures the linear relationship between two variables. It can be used for any data set that has a finite...
