Comparison of Photo Library Programs
Results
We used Microsoft Excel to do the statistical analysis of our data. Our experiment yielded sets of task times and subjective satisfaction scores for each of the photo library programs. Using this data we calculated means, standard deviations, and variances for each data set. We also used single factor ANOVA to test our data for statistical significance. The statistical information is presented both in charts and graphically below.
Task Times
The ANOVA test on the task times yielded a P-Value = .03 which was significant at alpha = .05. From this we can conclude that the differences in task times are statistically significant. See data appendices.
| Software | N | Mean | SD | Variance |
| PhotoFinder | 9 | 256.5556 | 57.28244 | 3281.278 |
| PhotoSuite III | 10 | 404.7 | 143.8194 | 20684.01 |
| ACDSee | 7 | 340.7143 | 117.0309 | 13696.24 |
Subjective Satisfaction
The ANOVA tests on the subjective satisfaction questions one through five yielded P-Values of 0.009, 0.282, 0.154, 0.061, 0.285 respectively. Using alpha = .05 we can conclude that only question one had statistically significant differences. See data appendices.
