 This section shows the results of the experiments described in section 3 on the data sets described in section 4. In the following pages, there 3 diagrams for each community. The diagrams capture 3 different aspects: the sentiment of answers, the vote score of questions, and the number of questions. These aspects are all measured concerning questions from new users.
 
-In diagrams (a), the blue line states the average sentiment (\emph{average sentiment} in diagram legend) of the answers to questions from new contributors. Also, the numbers attached to the blue line indicate the number of answers to questions from new users that formed the average sentiment. The orange line (\emph{sm single ITS} in the diagram legend) represents the ITS over the whole period of the available data. As stated in section 3.2, data density variability is a factor to take into account, therefore, the orange line represents the weighted ITS. The green, red, purple, and brown lines also represent ITS, however, the time periods considered for ITS before and after the change are limited to 6, 9, 12, and 15 months respectively.

-StackOverflow shows a very slight decrease in the average sentiment of time before the change is introduced. When the change occurs the average sentiment jumps up. After the change, the sentiments reach higher levels and keep rising. The average vote score rises right before and stays fairly constant after the change. This indicates that the vote score is not affected by the change. However, the number of questions from new contributors increases after the change while before the change is fairly constant. The number of follow-up questions from new contributors declines before the change and rises after the change.
+StackOverflow shows a very slight decrease in the average sentiment of time before the change is introduced. When the change occurs the average sentiment jumps up. After the change, the sentiments reach higher levels and keep rising. The sentiments improve after the change compared to before the change, indicating the change has a positive effect. 
 
-The sentiments improve after the change compared to before the change, indicating the change has a positive effect. The trend of the vote score is not affected at all. Although the change heightens the base level of the vote score, the trend is the same after the change, indicating the change did not bring a long-term effect. The amount of 1st questions improved after the change and turned the stagnant trend into an increasing trend. The follow-up questions also improved in the same manner. This shows that new contributors ask more questions than before. In summary, the sentiment improves, the vote score is largely unaffected, and the number of questions improves, suggesting that the community benefits from the change.
+The average vote score rises right before and stays fairly constant after the change. The rise of the vote score before the change indicates an outside factor other than the inspected change that improved the vote score.
