What this topic is
Judging validity / evaluating hypotheses asks whether the results of an ACT Science study actually support a stated conclusion.
A typical stem proposes a hypothesis and asks whether the data agree, with choices built as yes or no plus a reason. Both halves matter: a correct yes paired with a reason that misreads the data is still wrong. Questions also ask whether a conclusion goes beyond the evidence, for example claiming a result holds at temperatures that were never tested.
Valid conclusions stay within the conditions measured and rely on comparisons where only one variable changed. Checking the specific data point a reason cites is the reliable approach.
Every question is picked for where you are right now, wrong answers come back until they stick, and it all works offline.
