Wonderlic test is basically a standard test used at workplaces by managers or employers in order to determine the relative intelligence of the employee through a class of fifty question from each field to check the intelligence and aptitude to check the future performance of employees.
Wonderlic test may definitely help in checking the aptitude of employees but is is not an authentic predictor of future performance of employee because the standard questions asked in this test tends to cover only a small area or field of knowledge which cannot judge every performance aspect of the employee and fail to predict the capabilities accurately. Moreover it stresses on mathematical questions and reasoning which fail to predict the future performance of candidates at qualitative jobs or critical thinking activities.
The twelve short minutes to answer the questions might stress the applicants resulting in anxiety and mental , compromising the thinking capability thus producing incorrect results.
Guess work can unintentionally manipulate the result, so the topper might have gained 5 extra points out of guessing while the runner ups might have used their knowledge, again resulting in incorrect scoring.

Based on the Sporty Cars data, is "road test" a good predictor
of Price at the 95% confidence level?
Select one: a. No, the R^2 statistic indicates that only 30% of
the variability in price is explained by road test. b. No, the
F-statistic indicates that the regression does not explain price
significantly at the ninety five percent level. c. No, the
t-statistic indicates that the coefficient on road test is not
significantly different than zero at the 95% confidence...

Why does the correlation coefficient of a predictor increase
when we remove a relevant predictor in a multilinear regression?
For example, if we are regressing income on education, gpa, and
college rank and then remove college rank from the regression we
would see an increase on the correlation coefficient of education
and gpa. What is the intuitive explanation for this?
Similarly, we see a decrease in the correlation coefficients
when we add a variable. What is the reason for this...
