Explain what “rotation” refers to in exploratory factor analysis and explain when this is used.
In multivariate statistics, exploratory factor analysis (EFA) is a statistical methodused to uncover the underlying structure of a relatively large set of variables. EFA is a technique within factor analysis whose overarching goal is to identify the underlying relationships between measured variables.

Explain weighted factor analysis using concrete examples of weighted factor analysis from an unrelated topic useful if this concept is not familiar to you (the student). For example, what factors are considered when buying a new car? How much weight is each factor given?

How are exploratory data analysis (EDA) and hypothesis testing different? Explain why EDA could be preferred in data mining, and justify your explanation with a specific example.
Mark if true or false and justify in detail your response 1. Exploratory data analysis may not be used to check for relationships between variables in a data set.

Explain what synchronous rotation is. What is it caused by? Give an example. Answer: Synchronous rotation is when the rotational period of an object is the same as its orbital period around another object. As an object orbits another, it is stretched by the varying force of gravity across it. The resulting tidal bulges lag behind the rotational period becomes the same as the orbital period, at which point there is no longer any tidal friction and the rotational and...
