PPT-Effect of Power, Time, and Degassing on Sonication

A regression of the entire data set showed a significant threeway effect between power time and degassing Separate regressions were then run on the degassed and nondegassed samples Interestingly there were no significant interactions for the nondegassed samples but there was a significant twoway interaction between power and time for the degassed samplesp0035 .
