Research Summaries passages describe one or more experiments with tables linking trials to results—read the question first, locate the relevant experiment or table, and read for variables and controls only when design questions appear. They sit between Data Representation (pure figures) and Conflicting Viewpoints (pure reading). Part of the 3 ACT Science passage types.
What they look like
A researcher runs Experiment 1, Experiment 2, sometimes Experiment 3. Each has a short description and a table of results. Questions may ask about data, trends, or what was changed between trials.
Link tables to trials
Before answering, know which row or column corresponds to which condition. Questions often compare Trial A vs Trial B or ask what changed between experiments. Misidentifying the trial is the most common Research Summaries error.
Experimental design questions
When a question asks about controls, independent variables, or fair comparisons, read the experiment description—not the whole passage, just the setup for that trial. Vocabulary and traps in experimental design questions on ACT Science.
Figures-first still helps
Even with more text than Data Representation, most answers come from tables and graphs. Let questions tell you which experiment to read. Graph speed in reading graphs faster.
Trend and calculation questions
Research Summaries reuse the same question patterns as Data Representation: describe relationships, compute ratios, predict what would happen if a variable changed. See interpreting trends and calculating questions.
Do not import outside science
Answer only from what the passage states. If your biology class taught something different, trust the experiment description on the page. More in the science you actually need for ACT Science.
Start practicing
Start with a free diagnostic, then drill your weak spots with 15-question quizzes and track how you're doing across Reading, English, and Math. Compare plans whenever you're ready to go further.
