Top 10 Questions for Experimental Worker Interview

1. How would you design an experiment to test the effects of different fertilizer treatments on plant growth?

The steps to design an experiment to test the effects of different fertilizer treatments on plant growth could be as follows:

• Define the research question: What is the effect of different fertilizer treatments on plant growth?
• Establish a hypothesis: Different fertilizer treatments will lead to different levels of plant growth.
• Design the experiment: Select the experimental design and allocate treatments to plants.
• Conduct the experiment: Grow the plants under the different treatments and collect data on growth parameters.
• Analyze the data: Use statistical analysis to determine if there are significant differences in plant growth between the different treatments.
• Draw conclusions: Based on the results, determine if the hypothesis is supported or rejected.

2. What are the key factors to consider when selecting a statistical test for an experiment?

Here are some key factors to consider when selecting a statistical test:

• Type of data: The distribution of the data (e.g., normal, skewed) will affect the choice of test.
• Sample size: The size of the sample will affect the power of the test.
• Number of groups: The number of groups being compared will affect the choice of test.
• Type of hypothesis: The type of hypothesis being tested (e.g., one-tailed, two-tailed) will affect the choice of test.
• Significance level: The desired significance level (e.g., 0.05) will affect the choice of test.

3. How do you ensure the reproducibility of your experimental results?

To ensure the reproducibility of experimental results:

• Use appropriate experimental design: Follow established protocols and use appropriate controls.
