Comparison of responses amongst both groups. 2a shows mean number of correct responses per participant, along with standard error bars, for both control and intervention groups in their pretest and posttest. No significant difference is observed between the pretest in the mean number of correct responses for control vs. intervention groups. However, a statistically significant rise in mean number of correct responses is present in the posttest survey of the intervention group versus control, p< 0.001. 2b shows mean number of incorrect responses per participant, along with standard error bars, for both control and intervention groups in their pretest and posttest. No significant difference is observed in the mean number of incorrect responses for control vs. intervention groups. 2c shows the mean number of unsure responses per participant, along with standard error bars, for both control and intervention groups in their pretest and posttest. No significant difference is observed between the pretest mean of unsure responses for control vs. intervention groups. However, a statistically significant decline in the mean number of correct responses is present in the posttest survey of the intervention group versus control, p< 0.001.
