Risk Factors for School Absenteeism and Dropout: A Meta - PubMed LINGAIAH. The dependent variable is the element which is being measured in an experiment or evaluated in a mathematical equation. To determine the dropout rate (a.k.a., attrition rate) of a study, divide the number of incomplete responses by the total number of participants who started the study. The measurable factor in an experiment is known as the: Q. The Dropout Factor: Keeping Our Kids in School - alibi By adhering strictly to single-factor experiments only one of the above comparisons would be made in any one experi ment. Notice that instead of scaling the output by keep_prob in the prediction, we scale the weight by 1/keep_prob in the training phase. To reduce the risk for these problems it is important to gain insight into risk factors for both school absenteeism and permanent school dropout. 2. Q.
