Explain Why Two Results Need Not Conflict

Compare context and measurement before choosing between accounts.

Supplied materials

  • Original fictional Source A: “In a quiet practice room, eight of ten participants completed the diagram-only folding task.” Source B: “At a busy drop-in table, five of ten participants completed a different folding task with written instructions.” The tasks, settings, and participants differed; neither source tested both formats under the same conditions.
  • Paper and pencil; spoken responses are welcome.

Learn the idea

A synthesis explains relationships between sources, including why superficially different findings may not answer the same question. Both accounts report task completion, but the settings, tasks, and people differ. A higher count in A does not isolate the diagram format as its cause. Describe the contexts before drawing a comparison.

The two results can both be accurate while leaving a format decision unresolved. Eight of ten in one situation and five of ten in another establish those recorded outcomes. To compare formats more directly, the task and setting should be comparable, and the participants’ relevant starting conditions should be considered. A useful synthesis retains findings rather than erasing them because a comparison is limited.

  1. Record each source’s count, format, task, and setting.
  2. List at least two differences other than format.
  3. Write a sentence preserving both outcomes.
  4. Explain why the counts alone cannot determine the better format.
Worked example

See the method in action

A reports eight of ten completions with diagrams in a quiet room; B reports five of ten with written instructions at a busy table on a different task. Both findings stand, but the differing conditions prevent attributing the gap solely to format. A comparable-task trial would address the format question more directly.

Which synthesis best fits the evidence?

Feedback appears here after you check. This is practice, not a graded school assessment.

See the answer and explanation

The recorded counts differ, but task, setting, and participant differences leave the format effect unresolved.

The synthesis retains the measurements and relevant limits. Different conditions do not invalidate the counts or isolate one causal explanation.

Take it further

Change B to the same task and quiet room, but keep different participants. Model: task and setting are now more comparable, yet participant differences remain a possible explanation. Revise the limitation rather than claiming all uncertainty has disappeared.
