Guide to variable names in data file |Column |Variable Name |Description | |1 |case |Participant identifier | |2 |gender |0 = female, 1= male | |3 |stats |0 = no statistics courses, 1 = one or more | | | |statistics courses | |4 |numeracy |Score (out of 10) on the numeracy test | |5 |age |Participant's age in years | |6 |alphaorder |Order of the four alpha level conditions: | | | |1 = .25, .10, .40, .05 | | | |2 = .10, .05, .25, .40 | | | |3 = .40, .25, .05, .10 | | | |4 = .05, .40, .10, .25 | |7 |townorder |Order of the four town name conditions: | | | |1 = Grand Prairie, Townsville, Cedar Hills, | | | |Brook Hollow | | | |2 = Townsville, Brook Hollow, Grand Prairie, | | | |Cedar Hills | | | |3 = Cedar Hills, Grand Prairie, Brook Hollow, | | | |Townsville | | | |4 = Brook Hollow, Cedar Hills, Townsville, | | | |Grand Prairie | |8 |avgorder |Order of the four rainfall mean totals: | | | |1 = 30, 25, 40, 35 | | | |2 = 25, 35, 30, 40 | | | |3 = 40, 30, 35, 25 | | | |4 = 35, 40, 25, 30 | |9 |responseorder |Order of capture probability estimates for | | | |ranges of differing size: | | | |1 = +/- 3 in., +/- 6 in., +/- 9 in. | | | |2 = +/- 9 in., +/- 6 in., +/- 3 in. | |10-21 |a#r# |Percent estimates of capture probability | | | | | | | |"a" stands for alpha level | | | |"r" stands for range | | | | | | | |Ex. "a40r3" is the participant's capture | | | |probability estimate for the +/- 3 inch range, | | | |following receipt of a prediction level with a | | | |.40 alpha level. | |22-45 |a#r#actual |Actual capture probabilities (assuming a normal| | |a#r#error |distribution) and estimation error (estimate - | | | |actual). | | | | | | | |Ex. "a40r3actual" is the capture probability | | | |for the +/- 3 in. interval that is implied by | | | |the prediction interval with a .40 alpha level.| | | | | | | |Ex. "a40r3error" is the raw error in the | | | |participant's estimate for the +/- 3 inch | | | |interval, following receipt of a prediction | | | |interval with a .40 alpha level (i.e., a40r3 - | | | |a40r3actual). |
