It is appropriate because the estimated year is given in response after being asked when one thought the actual year the event occured and the actual year is explaining when it happened
The scatterplot would have been a straight diagonal line going from the bottom left to the top right of the graph.
I used the Union membership as the explanitory variable when relating the number of strikes and lockouts with the percentage of total labor force with union membership because I feel as though the membership is important to keep in mind when talking about the percent of members on strike.
Although there are some spots where this isn't true, for the most part as union membership rises so does the amount of strikes and lockouts.
My second scatterplot shows the number of strikes and lockouts over the course of 60 years.
The second scatterplot suggests that as the years went on, strikes and lockouts have decresed dramaticly from over hundreds in the early 50's to less then 50 every decade since 1990.
The bar graph helps compare the huge gap between the two salaries in the different states.
The association between the variables in your scatterplot is that they both refer to salary and the amount of money made.
There aren't really any trends to be seen in the graph, as one goes up the other seems to be just as random as it was before.
There's one point where, when the governor's salary is around $150,000, the Per Capita Personal Income is significantly higher, getting the closest to $60,000 when compared to all the other points.
