| self_rate_avg | the average self-rating on the level of understanding of eight aspects of financial literacy (i.e., budgeting, saving, managing debt, investing, retirement planning, taxation, insurance, and superannuation) each on a five-band Likert scale (i.e., 1 – very low, 2 – low, 3 – fair, 4 – high, and 5 – very high) |
| test_overall | the total number of correct answers to a panel of 14 quizzes on various aspects of financial literacy |
| rescaled_test_overall | Rescaled test_overall to a range between 1 and 5: rescaled_test_overall = 4 x test_overall / 14 + 1 |
| overconfidence | overconfidence in financial literacy: overconfidence = self_rate_avg - rescaled_test_overall |
