III. Describe which measure of central tendency-mean, median, or mode-was probably used in each situation. 1. One-half of the factory workers make more than 268.50 pesos per hour, and one-half make less than 268.50 pesos per hour. 2. The average number of children per family in the Plaza Heights Complex is 1.8. 3. Most people prefer red convertibles over any other color. 4. The most common fear today is fear of speaking in public. 5. The average age of college professors is 42.3 years.
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.
