"I could not find where to view my score" | The score display is not available and the score board design is not properly aligned. |
"The success messages are not obvious enough for the users" | Change the font size or color of success messages. |
"Accept and Reject buttons are not readable" | Change the font size and color of the buttons |
"The rules for knowledge are not easy and hard to remember" | Will implement 'Help' in later sprint when major functions are done |
"The navigation bar in Knowledge Challenge takes up too many spaces and is not professional" | Change to hidden navigation bar at bottom |
"There are too many unnecessary information in Scoreboard, which makes the overall design very crowded" | Limited the information displayed in Scoreboard and shift it to the left of the screen |

T-test Analysis
Since two different groups of participants test our System A and System B, therefore we ran the statistical standard T-Test for between subjects.
- Test: Two-tailed t-test at 95% significance level (α=5%)
- Independent Variable: System A vs. System B
- Dependent Variable: Mean time taken to complete the Ask Question task
- Let μ0 be the mean time to complete the task using System A(control).
- Let μ1 be the mean time to complete the task using System B(treatment).
- Hypotheses:
- Null Hypothesis h0: μ0≠μ1
- Alternative Hypothesis: h1: μ0=μ1
- P-value:
- As calculated using Excel formula: T.Test(array1,array2,2,3), p≈0.02=4.9%
- p < α, then significant, not by chance.
- Therefore we do not reject H0.
- Conclusion: H0 is true and thus the mean time taken in completing the tasks is significantly different, not by chance.
