In the results and conclusions sections of a research paper about pre-delinquent behavior,
the researcher mentions the strong correlational relationship between the number of incidents of pre-delinquent behavior and the number of hours the mother works outside the home. What does the author imply by stating this? (Select all that apply.)
a. Some sort of test of correlation was performed and it reached statistical significance.
b. As number of hours worked outside the home varied, so did the frequency of incidents of pre-delinquent behavior.
c. Having a mother work many hours outside the home causes pre-delinquent behavior.
d. Incidents of pre-delinquent behavior cause mothers to work more and more hours outside the home.
e. As number of hours worked outside the home increased, so did the frequency of incidents of pre-delinquent behavior.
f. The researchers avoided a type II error, in relation to the association between these two variables.
g. The researchers operationalized the two study variables.
