Question Help Is a measure of 25 inches "far away" from a mean of 19 inches? As someone with knowledge of statistics, you answer "it depends" and request the standard deviation of the underlying data.(a) Suppose the data come from a sample whose standard deviation is 2 inches. How many standard deviations is 25 inches from 19 inches?(b) Is 25 inches far away from a mean of 19 inches?(c) Suppose the standard deviation of the underlying data is 4 inches. Is 25 inches far away from a mean of 19 inches?
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.
