Correlations (1) If it is noisy, you are interrupted more often, too. Empirical Evaluation in Informatics, Project, Group 3

Correlations (2) People working late at night getting less disturbed by noise. 6 a.m. - 10 a.m 10 a.m. - 2 p.m 2 p.m. - 6 p.m 6 p.m. - 10 p.m 10 p.m. - 2 a.m 2 a.m. - 6 a.m Empirical Evaluation in Informatics, Project, Group 3

Correlations (3) People who aren't alone at their workplace are more often disturbed by noise than people working alone. Empirical Evaluation in Informatics, Project, Group 3

Summary The following factors were determined: Number of people working in the same room Noise level Internal validity: Subjectively answered questions You can't say whether you're more productive if... External validity: Target group: students doing their homework or having a side job Less than 9% working more than 30 hours per week Empirical Evaluation in Informatics, Project, Group 3
