Greetings, I need to determine the trend for barometric pressure based on measurements taken at 15-minute intervals over a 3 hour period. A rise or fall trend occurs if the the pressure changes more than 0.1 kPa, and rapid rise or fall if pressure changes more than 0.2 kPa over a three hour period. Measurements are in kPa, ranging roughly from 97.00 to 104.00.
Haven't used my college math in over thirty years - just can't seem to remember this.
Any help in this area would be greatly appreciated.
