Question

question 4 1 pt which of the following are used to reduce the chance of reaching an incorrect conclusion? independent variables dependent variables repeated trials sample sizes

Explanation:

• Independent variables are factors manipulated in an experiment, not for reducing error in conclusions.
• Dependent variables are measured outcomes, not for reducing incorrect conclusions.
• Repeated trials involve conducting an experiment multiple times to account for random errors, which helps reduce the chance of an incorrect conclusion by getting a more consistent result.
• Sample sizes relate to the number of observations, but increasing sample size (not just having a sample size) helps; however, repeated trials directly target reducing error in conclusions by repetition. Among the options, repeated trials are used to reduce the chance of incorrect conclusions.

Answer:

C. repeated trials
