How "voted a mixture of for and 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 1
MP voted against policy 0% 25 0
MP absent 50% 25 2
Less important votes MP voted with policy 100% 5 0
MP voted against policy 0% 5 3
MP absent 50% 1 2

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) = 51.0 / 92 = 55%.

And then this average agreement score
