Estimated vs Actual Dates of World Events
  1. The explanatory variable drives the value of the response variable. As the explanatory variable varies, the value of the response variable changes in response. Because we are measuring the estimated dates in relation to the actual dates, it makes sense that if the actual date were to change, our percieved estimation would change as well in order to more closely match the accurate date.
  2. If I had guessed the correct year for each date there would only be one set of points that match up with the actual dates. My accurate guesses would have fallen right on top of the actual dates creating one set of points.
Union Data by Percentage
Union Data by Year
  1. I used number of strikes and lockouts as the explanatory variable because it is the independent variable.
  2. As the number of Strikes and lockouts increases the union membership percentage increases.
  3. The second scatterplot represents the number and strikes and lockouts per year.
  4. The variables are roughly associated. The most common trend is that as we move closer towards present day, the fewer number of strikes and lockouts there are.
