Here is the info you need: Regression of height of children: 1. Y = 24.53 + 0.6377x Mean of height of children: 68.09 Mean heig
Inverse Normal Distribution
The method used for finding the corresponding z-critical value in a normal distribution using the known probability is said to be an inverse normal distribution. The inverse normal distribution is a continuous probability distribution with a family of two parameters.
Mean, Median, Mode
It is a descriptive summary of a data set. It can be defined by using some of the measures. The central tendencies do not provide information regarding individual data from the dataset. However, they give a summary of the data set. The central tendency or measure of central tendency is a central or typical value for a probability distribution.
Z-Scores
A z-score is a unit of measurement used in statistics to describe the position of a raw score in terms of its distance from the mean, measured with reference to standard deviation from the mean. Z-scores are useful in statistics because they allow comparison between two scores that belong to different normal distributions.
Here is the info you need:
Regression of height of children:
1. Y = 24.53 + 0.6377x
Mean height of adults: 68.3
Height of Children measured in terms of deviations from its mean:
2. Y = -0.00001 + 0.6377X
Question: What fraction of the variation in the heights of children is explained by the heights of their parents?
