During the execution of a project, a project manager wanted to discover how the number of worked hours was affecting the quality of given tasks. For a two-month period, the following data was documented:
Which of the following describes the result?
A.
A negative correlation exists between the number of mistakes and the working hours.
B.
No correlation exists between the number of mistakes and the working hours.
C.
A low correlation exists between the working hours and the number of mistakes.
D.
A positive correlation exists between the number of mistakes and the working hours.
No Correlation. No correlation means there’s no clear relationship between
the variables. Visually, the dots will form no discernible pattern on the graph. In this case the number of mistakes has nothing to do with the number of hours worked.
The plotted points do not line up in a clear upward (positive) or downward (negative) trend; they’re scattered, indicating only a weak relationship between the two variables.
