Abstract

The purpose of this exploratory investigation was to determine whether birth order has an effect on intelligence. Seventy-four undergraduate students from Rowan University participated in my study. During class-time, I handed out a questionnaire with questions pertaining to the student's birth order within their family and SAT scores. The SAT scores served as a measure of intelligence. The SAT scores were broken into seven different ranges, between 800 - 1400 & above. The birth order variable was broken down into four levels; firstborn, middle child, youngest and only child. The different levels of birth order and SAT scores were compared to see if significant difference existed between the two variables. The Kruskal-Wallis test, a non-parametric one-way analysis of variance, was used to determine if a significant difference existed between intelligence and birth order. This test found that there was a significant difference found when comparing the different variables of birth order and intelligence.
