IV Income - categorical/nominal Student lot - LOW; Faculty lot - HIGH Original coding sheet IV Income - categorical/nominal Student lot - LOW; Faculty lot - HIGH DV car value - continuous, 1-5 scale

Chi-Square (categorical variables) coding sheet Transfer car values from original sheet, then recode as a categorical variable 1, 2 - LOW 3 - MEDIUM 4, 5 - HIGH Chi-Square (categorical variables) coding sheet IV Income - categorical/nominal Student lot - LOW; Faculty lot - HIGH DV car value - categorical / ordinal - L, M, H

Difference between the means coding sheet Transfer continuous car values from original sheet Difference between the means coding sheet IV Income - categorical/nominal Student lot - LOW; Faculty lot - HIGH DV car value - continuous, 1-5 scale
