Which action increases bias in an experiment?

Answer and explanation

Correct answer: Recording only results that support the hypothesis

Recording only results that support the hypothesis creates selective bias because contrary or different results are deliberately left out. This makes the conclusion unreliable. Repeating a procedure and recording all data generally improve reliability, while using the same instrument can reduce unnecessary variation between measurements. Exam tip: In an unbiased experiment, record both supporting and non-supporting results.
