State Education Rankings: The Best And Worst For Math And Science
All of the "well above average" states for math & science have > 75% unionization rate.
All of the "above average" states for math & science have > 75% unionization rate except Virginia.
Of the 9 "far below" average states, 6 have a unionization rate below 45%.
Clearly its not the unions causing schools to do poorly in math and science. Any suggestion that they are doesn't doesn't jive with the facts.
Interesting that you draw a conclusion without taking all of the data into account. Do you still want me to believe you are an astrophysicist, or are you going to claim to be a teacher now?
First, the obvious problems here. Your data on unionization is from 2008-2009, and the data on Math and Science is from 2011. Since they are from different years it requires us to make unwarranted assumptions about the data. Let us go ahead and make the assumption that the unionization rates remain more or less constant and see what we can determine.
The best test scores are in Massachusetts, which happens to have a high unionization rate. The worst is Mississippi, which has a low unionization rate. So far, so good. Unfortunately, for you, the data shows that CA, NV, OR, WA, and KS, among others, also have a high unionization rate, and have test scores in Math and Science that are from below average to far below average. It also shows that Virginia, which has a very low unionization rate, has high test scores.
That makes your conclusion full of shit.
