You are just all over the map. First you claim 10 states have outlawed teacher's unions. Then when proven wrong due to the clear inability to comprehend your sources you post a link using decade old data and once again fail to comprehend what you are reading.
First, let's stay up to date with our data and not pick and choose years where we don't have all of the information. Secondly, do you know the percentile those states are in terms of taking the SAT exams?
South Carolina: 13
North Carolina: 16
Georgia: 5
Texas: 20
Virginia: 12
These states take the SATs at a much higher rate than other states. People who take the SATs tend towards the top of the educational system. States like Wisconsin who up until this year had one of the strongest public unions in the nation only have a participation rate of 5% with the SATs. They are 44th in the nation. Missouri also scores at the top percentile in exam scores, where our fearless Layla_Z teaches and has no union and is underpaid. You can't look at that number though because only 5% of the students actually take the exams.
These numbers mean absolutely nothing without looking at the participation rates, demographics and socio-economic conditions. In fact, The College Board (where your stats comes from) tells you so. Otherwise a state like Maine (95% participation) would be rated at the bottom in terms of education when it is not the case at all. You really have a lot of learning to do. You haven't made a single intelligent argument yet. Everything you've posted thus far has been a failure to comprehend what you have read or a bait and switch.. just like this argument.
Boo Radley: Thirty-something percent of public school teachers are in a union!!!11!!
> No Boo, your figure includes public as well as private employees from all different professions, not just teachers.
Boo Radley: Well, 10 states outlaw teacher's unions!!111!!
> No Boo, no state outlaws teacher's unions. They have a right to form a union. Some states haven't made collectively bargaining a requirement though.
Boo Radley: States that don't have collective bargaining have the lowest test scores and therefore the lowest quality education!!!!11!!
> No Boo, they take the exams at a much higher rate thus the numbers are skewed from the inclusion of students in much lower percentiles.
This entire thread has been nothing short of an exercise in futility with you. Basic reading comprehension and fundamental understanding of logic and recognizing fallacies is completely lost on you.
For your edification, here are the actual numbers for you to look at.

I'm really posting this for other people, I know you don't have the intelligence to comprehend the information.
