I researched the conditions that humidity and ozone changed (weather, sunlight, temperature). Then I formed my hypotheses, which was, "I think that if we have a high humidity there will be more ozone because the ozone would spread in the humidity."

Why did you choose to examine ozone with respect to humidity? What do you think would happen with ozone during the high humidity of the summer months?

Hello Katie Rose, If you were to research this question again, "How does a weather variable affect surface ozone" what modifications would you make? What additional data could you add to help you explore the relationship of surface ozone and weather phenomena?

Nice work, Katie-Rose! I am interested in your hypothesis - how did you decide that ozone would spread more in higher relative humidities? Also, I wanted to confirm about your units - were you measuring relative humidity as a percent? Or what units were you using when measuring humidity?

I look forward to reading your answers!
