Oz Farmer vs tValue

Oz Farmer is intended to assist farmers in every day calculations and record keeping. Oz Farmer provides various spray calibration tools that will allow you to calibrate your boom spray to achieve a specific application rate. It will also allow you to determine spray pressures to achieve the required spray output. There is also a tool to determine the total amount of liquid, chemical and tanks required to complete the spray job. Both Spray Calibration and Mixture Calculation results can be emailed for various record keeping requirements. Oz Farmer also allows the recording of chemical treatments of cattle, sheep, grains and crops and also determines the safe for slaughter and feed dates for specific treatments given the applicable withholding period. Treatment records can then be queried and exported for specific periods via email as an Excel spreadsheet. Oz Farmer has a gestation calculator that determines the expected due date after servicing for common farmed animals. Once the expected date has been calculated this can then be entered into the calendar for future reference and alerts. Oz Farmer has a conversion calculator to perform conversion between commonly used units (i.e. Acre to Hectares).

tValue can be used to quickly calculate unpaired Student t Values given two sets of mean, standard deviation and n. t values for difference from zero or other specified value can be calculated. Use the difference values for Set 1 and leave Set 2 blank for a paired t test.
