You participate in a study on workplace distractions. You design a study to assess how distractions affect productivity, and decide to do a formal experiment. You invite 20 students to spend 1/2 day a week, for one month, participating in the experiments. You choose an empty office for the experiment because you speculate that the quiet office environment will eliminate other types of distractions. During each half day, you interrupt them four times by, either dropping in for a chat, or sending them text notifications. You measure: . how long it took them to notice the distraction, that is how long it took to respond to the person walking into the room or to the text notification; how long it took them to get back to their work tasks after they had dealt with the distraction; how many tasks they were able to complete; their attentiveness to their work. In designing this study, you have identified attentiveness to their work as a potential: O a. A dependent variable O b. A control variable O c. A ranked variable O d. An independent variable O e.
