In statistics, a spurious correlation (also known as spuriousness) refers to a connection between two variables that appears to be causal but is not. With spurious correlation, any observed dependencies between variables are merely due to chance or are both related to some unseen confounding factor...

In a knowledge graph, nodes can be resources with unique identifiers, or they can be values with literal strings, integers, or whatever. The edges (also called predicates or properties) are the directed links between nodes. The “from node” of an edge is called the subject. The “to node...
Correlation means Causation. Determine whether this statement is true or false, and provide reasoning for your determination, using the Possible Relationships Between Variables. Give a real-life example of two variables that are likely to be negatively correlated. Explain...
Prescriptive analysis is a type of data analysis that’s used to determine the best course of action to take in a given situation. It involves using data and advanced algorithms to identify the actions that will have the greatest impact on a business’s performance and help it achieve its go...
A company that is spreading itself thinly across every social channel uses its social listening and analytics suites to determine that posts on LinkedIn and Twitter get far more engagement than on any other. As such, they decide to adjust their publishing frequency to focus solely on those more...
