From the following situations, which one identifies the independent variable and dependent variable correctly? a) The more time peoplespend using social media, the less able they are to express themselves in conversation. The independent variable is the expression in conversation while the dependent variable is the time spent using social media. b) Taking a nap in the afternoon makes people more relaxed andless irritable for the rest of the day. The independent variable is the level ofrelaxation and irritability of a personfor the rest of the day while the dependent variable is taking a nap in the afternoon. c) Therelationship between the amount of violence that children see on television and the amount of aggressive behavior they display. The independent variable is amount of aggressive behavior display by children while the dependent variable is the amount of violence that children see on television.

The following data were obtained from a research study examining the effect of sleep deprivation on motor-skills performance. A sample of n = 5 participants was tested on a motor-skills task after 24 hours of sleep deprivation, tested again after 36 hours and tested once more after 48 hours. The dependent variable is the amount of errors made on the motor-skills task. Do these data in the indicate number of hours of sleep deprivation has a significant effect on motor skills performance?
