[2025-09-30T11:27:51.027078] [PI reasoning] **Determining statistical test**

I need to provide the best statistical option and a brief reasoning for it. In this case, we’re comparing mean peak expiratory flow rates across non-smokers, light smokers, moderate smokers, and heavy smokers. Since we're assessing more than two independent groups with a continuous outcome, the correct statistical test is a One-way ANOVA. I might consider adding citations for clarity, perhaps referencing a general statistics textbook or an article on ANOVA's application in lung function studies.

[2025-09-30T11:30:25.676707] [PI reasoning] **Crafting ANOVA reasoning**

The thought starts by noting that a study mentioned a "one way ANOVA test" regarding the relationship between pack-year and pulmonary function. It highlights their use of one-way ANOVA to compare pulmonary function across different pack-year categories, which is insightful. I’ll cite Chowdhury 2021 for this. Based on these observations, for comparing means of a continuous variable across multiple independent groups, the one-way ANOVA is indeed the appropriate method. Now, I’ll work on the final answer.
