Question

does this describe an observational study or an experiment?

the temperature on randomly selected days throughout the year were measured

• observational study
• experiment

Explanation:

🆕 New Concept Discovered: Observational Studies vs. Experiments
Distinguishing between active intervention and passive measurement.

Step 1: Analyze the definitions

To determine whether a study is an observational study or an experiment, we look at whether a treatment or intervention was actively applied to the subjects:

• Observational Study: Researchers observe and measure characteristics of interest without attempting to modify or influence the subjects being studied.
• Experiment: Researchers actively apply some treatment or intervention to the subjects and then observe its effects.

Step 2: Apply to the scenario

In this scenario, the temperature on randomly selected days throughout the year was measured.

• The researchers did not influence, control, or alter the weather or the temperature of the days.
• They simply recorded (observed) the natural temperature values that occurred.

Because there was no active intervention or treatment applied, this is an observational study.

Answer:

Observational Study
