question 6 of 25
at what stage of an experiment is a hypothesis formed?

a. after it is complete

b. in the middle

c. at several intervals throughout

d. before it starts

Explanation:

In the scientific method, a hypothesis is a proposed explanation or prediction made before an experiment begins. It guides the experimental design and data collection. So a hypothesis is formed before the experiment starts. Option A is incorrect as hypotheses aren't formed after completion. Option B and C are also incorrect as the hypothesis is part of the planning phase before the experiment, not during or at intervals.

Answer:

D. Before it starts
