State whether the investigator used
independent samples, repeated measures, or matched samples:
An investigator wants to know if elementary-age
children who have experienced the death of a parent are helped by a counseling
group consisting of other children who have experienced a death in the family.
He randomly selects children for this special counseling group, comparing their
emotional adjustment at the beginning of treatment with their emotional adjustment following a year of group counseling.
the investigator used repeated measures, since he/she wants to know a specific group with disparity dependent on one factor i.e., emotional aspect. many samples are taken repeatably to ascertain the fact they are helped by counseling group consisting of children who have experienced death in a family.
