   Question

   In an experiment, participants were randomly divided into two groups (group variable: ERROR_APPROACH) who had to perform a task. The two groups were instructed differently beforehand: error prevention (” you are not allowed to make mistakes” ) and error management (” you are allowed to make mistakes make mistakes, you learn from them”). Below is a series of AN(C)OVA analyses TRUE examined whether error-approach affects how well the task was performed (PERFORMANCE). SELFCONTROL (degree of self-discipline, measured prior to the experiment) is a covariate in these analyses a covariate.

   

   Which statement is true for the population?
   1: Participants in the ‘error management’ group, prior to the experiment in self-discipline from those in the ‘error prevention’ group 2: Taking into account existing differences in self-discipline, the error management instruction leads to higher performance on the task task than the ‘error prevention’ instruction
