Rubric and model report
Part 1 (3 marks)
Model: “Does writing three good things each night raise my daily well-being rating? Dose: every night for four weeks, before bed.”
Part 2 (5 marks)
Model: baseline mean 5.4; weeks 3 and 4 mean 6.1; change 0.7; adherence 79% (22 of 28 days); missed days noted (travel, illness).
Part 3 (3 marks)
Model: “My rule asked for a change of at least 1.0; I measured 0.7, so the rule was not met.”
Part 4 (4 marks)
Model: no comparison group; expectation (I knew the habit was meant to help); regression to the mean (my baseline may have been a low stretch); concurrent events (exams, travel); one person, one scale.
Part 5 (3 marks)
Model: “I will retest for four more weeks with a comparison period, adding an if-then plan from M7.L3, and I will keep adherence above 90%.”
Part 6 (2 marks)
Check: no “raised” or “caused”, numbers as measured, unhelpful results reported, no low days deleted.
