A researcher investigated the effect of sleep deprivation on spatial navigation. Participants were split into two groups: a Sleep-Deprived group and a Well-Rested group. Each participant completed a virtual maze, and the number of navigation errors they made was recorded.
Calculate the mean number of navigation errors made by the Sleep-Deprived group and the Well-Rested group, and complete Table 1 with your answers.
You must give your answers to one decimal place.
