Instructions: Use technology to find statistical measures. Round to the nearest hundredth. Data Set: 24.0, 24.3, 25.9, 18.9, 27.5, 17.9, 21.8, 20.9, 16.7, 27.3 18.2, 24.7, 20.0, 22.6, 23.9, 18.0, 31.4, 22.3, 24.0, 25.5 24.7, 24.6, 28.1, 24.9, 22.6, 23.6, 23.4, 25.7, 24.8, 25.5 What is the population mean? What is the population variance? What is the population standard deviation?
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.
