The independent variable in the Stroop Effect experiment is whether the color word matches or mismatches the color of the ink. The dependent variable is reaction time. It is hypothesized that reaction time will be lower for color-word matches than mismatches. Descriptive statistics on the dataset show higher mean and variability for the incongruent condition. A t-test was conducted and found a statistically significant difference between conditions, rejecting the null hypothesis. This matches expectations that it takes longer to name a color when it mismatches the written word.
