homework assignment 2.2
which of the following is the goal of a descriptive study?
select an answer and submit. for keyboard navigation, use the up/down arrow keys to select an answer.
a establish causation between two or more variables

Explanation:

For 2.1: The scientific method starts with identifying a problem by asking a question, which is the stage where a problem to solve is proposed. Observation leads to the question, experiment tests hypotheses, and analysis interprets results.
For 2.2 (partial question): A descriptive study focuses on describing characteristics or phenomena of a subject, not establishing causation (that is for experimental studies).

Answer:

2.1: a. When asking a question
2.2: (The full options are not provided, but the correct goal of a descriptive study is to describe features of a group, situation, or phenomenon, so the option matching this description would be the answer; the listed option "Establish causation between two or more variables" is incorrect.)
