The ozone data set contains 8 hour ozone readings from the Mecklenburg County Line Site from 1990-1997.  This monitoring station is located within one mile of Charlotte (Lowes) Motor Speedway and has the highest average ozone readings among all ozone monitors in both Carolinas.  The data include, in addition to ozone readings, daily max temperatures, humidity, and average wind speeds.

Requirement:

• Download the ozone data set from the course web site.

• Conduct three single factor ANOVA's for the effect of temperature, wind speed and humidity respectively on ozone concentration.
• For each variable:
• Sort the data based upon that variable
• Group the data by levels of that variable
• Establish a separate column for each grouped level
• Copy and paste the ozone readings for each group to the approprate column
• Use the entire block of pasted data for your ANOVA analysis.

 
• Using your results, write a summary that clearly interprets your results concerning the effect of each variable (maximum daily temperature, average wind speed, and % relative humidity) on ozone concentrations at the County Line site

 
• Calculate the % of total variance in ozone concentrations that can be explained for each grouping of variables.
