An article reported on the physical characteristics of Division I starting football players in the 1988 season. Information for teams ranked in the top 20 reported a mean weight of starters on the top-20 teams was 105 kg, with a standard deviation of 16.3 kg. A starting football player for Texas A&M weighed in at 110.5 kg. Which of the following is the correc calculation for the z-score for this football player? O z= 105-110.5 33 O z= 110.5-33 105 O z= 33-105 110.5
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.
