EXAMPLE OF REAL TIME DATA PROJECT #1


Students retrieve necessary real time data and perform conversions to complete their OZONE TABLE. A minimum of six cities must be used.


OZONE DATA TABLE - Real Time Data from August 3, 1999

Latitude Longitude Latitude Longitude        
August 3, 1999 degrees minutes degrees minutes decimal degrees Dobson Units Temperature UV-Index Weather

AS CREATED IN MICROSOFT EXCEL '97


Students graph data to discover relationships that occur between variables. (These graphs were created with Microsoft Excel '97)
 
ChartObject Dobson Units vs. UV Index
Graph #1
Apply a straight trend line.

Express line as an algebraic equation.

 

ChartObject Latitude vs Temperature
Graph #2
Apply a polynomial trend line.

Compare to Graph #3

What would this graph look like in January?

ChartObject Latitude vs Dobson Units
Graph #3
Apply a polynomial trend line.

Compare to Graph #2

What would this graph look like in January?

ChartObject Dobson Units vs Temperature
Graph #4
Describe any apparent trends.  These are not obvious trends but may be present.

More data may be helpful.

ChartObject UV-Index vs Temperature Graph #5
Predict expected trends.  Do you see your predictions in the graph.

Can you explain outliers with your current weather data?
 


 
Predicting your UV-Index

Hoboken, New Jersey (August 3, 1999)
Lat/Long = 40.73 North, 74.02 West
Ozone = 324 Dobson Units



UV-Index = -0.1428(Dobson units) + 52.418
UV-Index = 6.15
Real Time Data UV = 7
