About
This dataset explores the complex relationship between parental factors and child intelligence, alongside investigating the nature versus nurture debate in IQ development. It is primarily designed for predicting a child's intelligence quotient (IQ) based on various maternal attributes, including age at childbirth, IQ, and education level. The collection also includes data from a unique twin study that tracked identical twins separated at birth, one raised by biological parents and the other in a foster home, with both receiving IQ tests to assess the impact of environment versus genetics. Additional data covers a child's analytical skills scores in relation to both mother and father's IQs. This resource originates from the Department of Statistics at Columbia University in NYC, with specific parts of the twin study attributed to Graybill and Iyer's 1994 research.
Columns
The dataset is structured across several files, with detailed information available for
child_iq.csv and kid_iq.csv.- Child IQ Score: Represents the child's intelligence quotient or test score, typically ranging from 101 to 400.
- ppvt: Measures the child's test score, with values ranging from 20.00 to 144.00, and a mean of 86.9.
- educ_cat: Categorises the mother's education level, where 1 signifies no high school education, 2 indicates high school graduation, 3 denotes some college, and 4 represents a college graduate. The mean education level is 2.11.
- momage: Records the mother's age at childbirth, with ages ranging from 17 to 29 years and a mean age of 22.8.
- Other files, such as
gifted.csv, include a child's analytical skills test score, mother's IQ, father's IQ, and additional related features. Thetwins.csvfile contains IQ test results for identical twins raised in differing environments.
Distribution
This data product consists of four distinct datasets:
child_iq.csv, kid_iq.csv, gifted.csv, and twins.csv. The child_iq.csv file, for instance, contains 400 valid records across its four columns. The data is provided in a standard CSV file format, making it easily accessible for various analytical tools. No missing or mismatched data has been reported for the detailed columns.Usage
This dataset is highly suitable for:
- Developing predictive models for child IQ based on parental characteristics.
- Conducting statistical analysis to understand the influence of parental age, education, and IQ on offspring intelligence.
- Researching the nature versus nurture debate in the context of intelligence, particularly through the unique twin study.
- Social science and education research focused on developmental psychology and family influences.
- Applying regression analysis to identify significant factors affecting child cognitive development.
Coverage
The data primarily covers demographic information pertaining to children, mothers, and fathers, including specific insights into identical twins. Geographically, some data originates from Columbia University in New York City. The twin study component tracks individuals from the mid-20th century, with the study itself by Graybill and Iyer being published in 1994. The twin study specifically focuses on individuals separated at birth and raised in distinct home environments.
