Sample interview questions: How do you approach the process of designing experiments to test hypotheses?
Sample answer:
Approach to Experiment Design for Hypothesis Testing:
-
Define Clearly: State the hypothesis to be tested in unambiguous terms.
-
Identify Variables: Determine the independent (manipulated) and dependent (measured) variables that are relevant to the hypothesis.
-
Control Variables: Identify extraneous variables that could influence the results and implement measures to control or eliminate their effects.
-
Choose Appropriate Design: Select an experimental design that maximizes statistical power and minimizes bias. Consider using randomized controlled trials, single-blind or double-blind studies, and appropriate controls.
-
Determine Sample Size: Calculate the minimum sample size required for statistical significance, considering the effect size, level of significance, and power of the test.
-
Establish Measurement Methods: Validate the reliability and accuracy of the methods used to measure the dependent variable.
-
Data Collection and Analysis: Conduct the experiment meticulously,… Read full answer
