How "voted generally against" is worked out
They Vote For You gives each vote a score based on whether the MP voted in agreement with the policy or not. These scores are then averaged with a weighting across all votes that the MP could have voted on relevant to the policy. The overall average score is then converted to a simple english language phrase based on the range of values it's within.
When an MP votes in agreement with a policy the vote is scored as 100%. When they vote against the policy it is scored as 0% and when they are absent it is scored half way between the two at 50%. The half way point effectively says "we don't know whether they are for or against this policy".
The overall agreement score for the policy is worked out by a weighted average of the scores for each vote. The weighting has been chosen so that the most important votes have a weighting 5 times that of the less important votes. Also, absent votes on less important votes are weighted 5 times less again to not penalise MPs for not attending the less important votes. Pressure of other work means MPs or Senators are not always available to vote – it does not always mean they've abstained.
| Type of vote | Agreement score (s) | Weight (w) | No of votes (n) | |
|---|---|---|---|---|
| Most important votes | MP voted with policy | 100% | 25 | 0 |
| MP voted against policy | 0% | 25 | 1 | |
| MP absent | 50% | 25 | 1 | |
| Less important votes | MP voted with policy | 100% | 5 | 1 |
| MP voted against policy | 0% | 5 | 2 | |
| MP absent | 50% | 1 | 1 | |
The final agreement score is a weighted average (weighted arithmetic mean) of the scores of the individual votes.
Average agreement score = sum(n×w×s) / sum(n×w) = 18.0 / 66 = 27%.
And then this average agreement score
- between 95% and 100% becomes "voted consistently for"
- between 85% and 95% becomes "voted almost always for"
- between 60% and 85% becomes "voted generally for"
- between 40% and 60% becomes "voted a mixture of for and against"
- between 15% and 40% becomes "voted generally against"
- between 5% and 15% becomes "voted almost always against"
- between 0% and 5% becomes "voted consistently against"
