Developmental Age, determined by calculating the results of the GDO-R, is an age in years and half-years that best describes a child's behavior and performance on a developmental scale. It may be equal to, older, or younger than the child's actual chronological age. It encompasses a child's social, emotional, intellectual and physical make up.
The goodness of fit of a statistical model describes how well it fits a set of observations. Measures of goodness of fit typically summarize the discrepancy between ...
For a test of goodness-of-fit, df = Cats − Params, where Cats is the number of observation categories recognized by the model, and Params is the number of parameters in the model adjusted to make the model best fit the observations: The number of categories reduced by the number of fitted parameters in the distribution.
Vygotsky, a Russian theorist, proposed the sociocultural theory of child development. During the 1920s–1930s, while Piaget was developing his own theory, Vygotsky was an active scholar and at that time his theory was said to be "recent" because it was translated out of Russian and began influencing Western thinking.

The incidence and quality of physical activity education in early childhood education have a strong positive effect on the cognitive, social and physical development of young children. [12] Early childhood is a stage of rapid growth, development and learning and each child makes progress at different speeds and rates. [13]
Holistic development sees the child in the round, as a whole person – physically, emotionally, intellectually, socially, morally, culturally and spiritually. Learning about child development involves studying patterns of growth and development, from which guidelines for 'normal' development are construed.
The Maturational Theory of child development was introduced in 1925 [1] by Dr. Arnold Gesell, an American educator, pediatrician and clinical psychologist whose studies focused on "the course, the pattern and the rate of maturational growth in normal and exceptional children"(Gesell 1928). [2]
In statistics, deviance is a goodness-of-fit statistic for a statistical model; it is often used for statistical hypothesis testing.It is a generalization of the idea of using the sum of squares of residuals (SSR) in ordinary least squares to cases where model-fitting is achieved by maximum likelihood.
