How can bias be reduced in scientific observation?

Answer and explanation

Correct answer: By recording all results according to the same predetermined rule

To reduce bias, every observation or result should be recorded using the same rule decided in advance. This reduces selective recording and makes the conclusion more objective. Recording only expected results increases bias. Exam tip: In unbiased observation, record all relevant data, whether or not they support the hypothesis.
