<h3><u>What is a "natural join"?</u></h3>
By default, natural joins are natural inner joins, however, they can also be natural left, right, and full outer joins. The main distinction between an inner join and a natural join is that an inner join has a join condition that is specified explicitly, whereas a natural join's conditions are determined by matching all pairs of columns in the tables that have the same name and compatible data types, which makes natural joins equijoin because the join condition is equal between common columns.

Answer:
Construct validity
Explanation:
Construct validity is the extent to which a research or test conducted measure what it claims to be measuring. This method of validity is established when researchers correlative their findings with other measures and then shows that the measures are associated in some way that is predictable by theory. A usual example of this is the measurement of the brain such as ability, emotion level, and/or intelligence level. Professor Tyler establishes a form of correlation between authoritarianism with voting behavior and child rearing. This shows construct validity.
