Sample Standard deviation = ________________________ c. sample Variance = ________________ X P(x) 57 inches 1/2 59 inches 3/22 59.50 inches 1/22 60 inches 1/22 61 inches 5/22 61.20 inches 3/22 62 inches 1/22 63.2 inches 1/22 63.6 inches 1/22 64 inches 1/22 64.8 inches 1/22 65 inches 1/22 69 inches 1/22
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.
