For instance, based on a correlation alone, it would be just as reasonable to believe that windmills cause wind as it would be to believe wind causes windmill blades to turn. Structural modeling; Covariance algebra; Principles of path analysis; Models with observed variables as causes; Measurement error in the exogenous variable and third variables; Observed variables as causes of each other; Single unmeasured ... In other words, they are interested in studying what factors influence who much formal schooling and degrees a person will achieve in their lifetime. Spurious Correlations. When you look at historical trends in educational attainment as measured by race, you see that Asian Americans between the ages of 25 and 29 are most likely to have completed college (a full 60 percent of them have done so), while the rate of completion for White people is 40 percent. correlations appear only due to the size, not the nature, of data.
