Why You Need It
Sampling error can be the largest source of error in any assessment. If the error is too large, incorrect characterization can result because the samples are not representative. The best designed sampling plan is of little use if the samples are not properly collected. That’s why you need an understanding of correct sampling principles and an ability to correctly apply them to your assessment.
EnviroStat offers open enrollment courses and provides customized in-house training to meet specific needs.
