Polygenic Traits01:18

Polygenic Traits

66.3K
When more than one gene is responsible for a given phenotype, the trait is considered polygenic. Human height is a polygenic trait. Studies have uncovered hundreds of loci that influence height, and there are believed to be many more. Due to the high number of genes involved, as well as environmental and nutritional factors, height varies significantly within a given population. The distribution of height forms a bell-shaped curve, with relatively few individuals in the population at the...

Variation: Normal Distribution, Range, and Standard Deviation02:32

Variation: Normal Distribution, Range, and Standard Deviation

22.4K
In the field of psychology, there are several ways to organize measurements of a trait, feature, or characteristic (i.e., variables). Qualitative data, such as ethnicity, can be tabulated into a frequency count to provide information about the proportion, as well as the variety of groups in a sample or population. On the other hand, researchers can perform a wider set of calculations on quantitative data. The mean, mode, and median, for instance, are central tendency measures to identify a...

Multiple Regression01:25

Multiple Regression

3.1K
Multiple regression assesses a linear relationship between one response or dependent variable and two or more independent variables. It has many practical applications.
Farmers can use multiple regression to determine the crop yield based on more than one factor, such as water availability, fertilizer, soil properties, etc. Here, the crop yield is the response or dependent variable as it depends on the other independent variables. The analysis requires the construction of a scatter plot...

Nature and Nurture01:10

Nature and Nurture

20.6K
Many human characteristics, like height, are shaped by both nature—in other words, by our genes—and by nurture, or our environment. For example, chronic stress during childhood inhibits the production of growth hormones and consequently reduces bone growth and height. Scientists estimate that 70-90% of variation in height is due to genetic differences among individuals, and 10-30% of variation in height is due to differences in the environments that individuals experience,...

Regression Toward the Mean01:52

Regression Toward the Mean

6.3K
Regression toward the mean (“RTM”) is a phenomenon in which extremely high or low values—for example, and individual’s blood pressure at a particular moment—appear closer to a group’s average upon remeasuring. Although this statistical peculiarity is the result of random error and chance, it has been problematic across various medical, scientific, financial and psychological applications. In particular, RTM, if not taken into account, can interfere when...

Applications of Normal Distribution01:22

Applications of Normal Distribution

5.5K
The normal distribution is a useful statistical tool. One of its practical applications is determining the door height after considering the normal distribution of heights of persons, such that many can pass through it easily without striking their heads. The normal distribution can also determine the probability of a person having a height less than a specific height.
The heights of 15 to 18-year-old males from Chile from 1984 to 1985 followed a normal distribution. The mean height is 172.36...

Area of Science:

  • Orthopedics and Sports Medicine
  • Human Growth and Development
  • Biometrics

Background:

  • Accurate prediction of skeletal maturity and final height is crucial in pediatric orthopedics.
  • Existing methods for predicting sitting height at maturity have limitations in diverse populations.
  • Understanding spinal growth patterns is essential for managing skeletal conditions.

Purpose of the Study:

  • To develop and validate a multiplier method for predicting sitting height at skeletal maturity.
  • To assess the accuracy of this method across different percentiles, age groups, and ethnicities.
  • To evaluate the utility of the multiplier for predicting spinal segment lengths and growth post-fusion.

Main Methods:

  • Utilized longitudinal and cross-sectional clinical databases.
  • Calculated multipliers by dividing sitting height and spinal lengths (cervical, thoracic, lumbar) at maturity by corresponding measurements at each age and percentile.
  • Conducted comparative analyses of multipliers across percentiles and diverse racial/ethnic groups.

Main Results:

  • Developed multipliers for predicting sitting height and spinal lengths at maturity.
  • Demonstrated minimal variability in sitting height multipliers, correlating well with thoracic and lumbar spine multipliers.
  • Established the accuracy of the multiplier method as independent of generation, percentile, race, and ethnicity.

Conclusions:

  • The multiplier method provides an accurate and reliable approach to predict mature sitting height.
  • This method can also anticipate the mature lengths of the cervical, thoracic, and lumbar spine.
  • The multiplier is valuable for assessing the lack of spinal growth after fusion in skeletally immature individuals.
