Question

1. choose the best answer.

another way to reduce bias is to make sure an experiment is _.
random
fun
repeatable
systemic

Explanation:

• Randomness helps in distributing potential biases evenly among groups. In an experiment, if participants or elements are randomly assigned (e.g., in a random - controlled trial), it reduces the chance of systematic differences between groups that could introduce bias.
• Fun is not a scientific criterion for reducing bias.
• While repeatability (getting the same results when an experiment is repeated) is important for validity, it is not directly related to reducing bias in the experimental design itself.
• Systemic implies a pattern or a built - in (often negative) structure. A systemic experiment would likely have more bias rather than less.

Answer:

random
