What is the difference between a filter and a query?
A query is a function designed to output a response. A filter is a restriction designed to weed out irrelevant or unwanted responses.For example, if one were to google information on monks, but not the television show Monk, one might parse the query as: monk -tv -"Tony Shalhoub". The first term would be the query, and the next two terms (each marked with a minus sign) would be the filters.
How can you determine whether two variables x and y for a real life situation are correlated?
You calculate a correlation coefficient and test to see if it is statistically different from 0.
Why relational algebra is a procedural query language?
The syntax of a query in relational algebra essentially describes the query evaluation algorithm i.e. SELECT WHERE FROM --------------- I don't agree with the above answer. Notice that 'SELECT WHERE FROM' is fragmentary SQL. It does not describe an algorithm, or procedure, for obtaining the desired results. Rather, it describes the characteristics of the desired results and where they might be obtained. In fact, relational algebra is not inherently procedural. It involves closed collections of objects called relations and a set of permitted operations on these objects. Please see the link.
Correlations are an indication that causality is always present?
False. One of the most important rules to learn in statistics is that correlation does not equal causation. Just because two items or correlated, or linked, doesn't necessarily mean that one caused the other. For example, think about if every time you go out for a run it starts raining. Those two events may be correlated, but that doesn't mean you cause it start raining because you went for a run.

What is a nested query?
It is a query inside another query. Sometimes we might use one query to reduce down the amount of data to go through and then use another query based on the output of that query to get what you want. The first query is inside or nested in the first query.
What are subqueries used for in a database?
A subquery is basically a query inside another query. Sometimes a main query needs to process data that is the result of another query. To extract that data a subquery could be built into a field in a main query. This is known as a subquery.A subquery is basically a query inside another query.
