- A researcher is interested in the effects of birth order (first
born versus later born) on achievement in a group of middle school
boys and girls. The researcher believes that birth order has a
differential effect on achievement in boys and girls. Data were
collected on a standardized test taken by all students (both boys
and girls) in the 8th grade (higher scores indicate greater
achievement). The data are given below:
Only child, boys:
93,92,94
Only child, girls: 88,89,90
First-born, boys:
93,92,94
First-born, girls: 88,89,90
Later-born, boys:
88,87,86
Later-born, girls: 74,75,73
- Perform the appropriate analysis.
- Describe the findings fully using appropriate follow-up test
where necessary.
- Was the researcher's hypothesis supported?
