A researcher is investigating the effects of temperature on the hatch time of grouper (fish) eggs. The eggs are exposed to different temperatures and the time that it takes the eggs to hatch is measured. What is the dependent variable?

• the hatch time
• the temperature
• the species of grouper

Which of the following is NOT an example of researcher bias?

• A researcher selectively records data that supports their hypothesis while ignoring data that contradicts it.
• A researcher chooses observation sites that are easier to access but may not represent the overall study area.
• A researcher designs an experiment with clear, objective protocols to minimize personal influence on the results.
• A researcher unconsciously influences the outcome of an experiment due to their expectations about the results.

Marine biologists are measuring the nitrogen levels at 10 random locations within a bay to determine which direction the most nutrient runoff is coming from. Which type of graph will they use to present their results?

• a line graph
• a bar graph
• a histogram

If you categorize ocean organisms by "habitat" (e.g., reef, open ocean, estuary), what type of variable is this?

• Quantitative
• Continuous
• Categorical

Systematic error in an experiment can result from:

• Using calibrated instruments
• Misreading random samples
• Faulty equipment consistently reading 2°C too high
• Unexpected variability in natural systems

A study on fish populations only collects data near coastal areas. This could introduce:

• Measurement errors and bad results
• Sampling bias that reduces the strength of conclusions
• Observer error that can result in unreliable data
