Which of the following steps could you take to reduce error in your experimente select all that apply -- there are three correct options. Have only one person conduct the experiment. Use the same brand of lighting in each chamber. Ensure that all the chambers' gas analyzers are calibrated. Include both healthy and sick potatoes in the experiment. Keep the potato plants outside prior to the experiment. Use five different species of potato plants. SUBMIT

The correct options are:

1. Use the same brand of lighting in each chamber.
2. Ensure that all the chambers' gas analyzers are calibrated.
3. Have only one person conduct the experiment.

Explanation for each option:

1. Use the same brand of lighting in each chamber: This helps to ensure that the lighting conditions are consistent across all experimental setups, reducing variability that could affect the results.

2. Ensure that all the chambers' gas analyzers are calibrated: Calibration of gas analyzers ensures that the measurements are accurate and reliable, reducing measurement error.

3. Have only one person conduct the experiment: This minimizes variability in how the experiment is conducted, as different people might have slightly different techniques or interpretations of the procedure.

Incorrect options:

4. Include both healthy and sick potatoes in the experiment: This introduces additional variables that could affect the results, increasing the potential for error.

5. Keep the potato plants outside prior to the experiment: This could introduce uncontrolled environmental variables that might affect the plants differently, leading to inconsistent results.

6. Use five different species of potato plants: Using different species introduces genetic variability, which can affect the outcome of the experiment and increase error.

Summary: To reduce error in the experiment, you should use the same brand of lighting in each chamber, ensure that all the chambers' gas analyzers are calibrated, and have only one person conduct the experiment.
