Yeast/Mold Count and Calculations

In the location column of the Yeast/Mold data table, each corner along with each sample for both plots in those corners should be recorded. In the next column labeled dilutions, the lowest dilution number that has yeast should be recorded for each sample. in the next column labeled Yeast colony, the number of yeast colonies on the dilution recorded in the table should be recorded. On the next column labeled value A, the number recorded for each sample should be the number of yeast colonies x 10-2 x 10|dilution used|.

These values should then be recorded again in the next three columns labeled Dilution, Mold Colony, and Value B for mold instead of yeast for each sample.

In the last column labeled Total Calculated, the sum of Value A and Value B should be recorded in each space for each sample.

 Sulfate and Humus Data                                       

Location Sulfate Level(ppm) Humus (ordinal scale)
SE 1a 0 1
b 0 1
c 0 1.5
2a 0 3
b 0 3
c 0 2
Each corner along with each of the three samples in those two locations should be recorded in the first column. In the second column, the sulfate level found for each sample of soil should be recorded in the table. In the third column, the amount of humus found for each sample of soil should be recorded in the table.

 Fathom Scatterplots for Data

 

In a table the values for humus, sulfate, yeast, and mold found should be recorded for the first site. The same table should then be duplicated for the data from site 2.
The sulfate and humus levels should then be compared in a scatterplot for each site. Make sure Humus is on the x axis and that sulfate is on the y axis. Then add the least squared line in order to find the r squared value for the data on the graph.
Similar to the previous scatterplot, a new one should be created comparing humus and mold values. Two seperate plots should be made, one for each site. Be sure to use the calculated value for the mold data, and be sure to put the mold on the x axis and the Humus value on the y axis. Then add the least squared line on the graph in order to find the r squared value.
A third scatterplot for each site should also be created to compare the sulfate levels and the calculated mold values. Be sure to put the mold values on the x axis and the sulfate values on the y axis, and to add the least squared line in order to get the r squared value for the data.
