MEASURES OF CENTER: Start with the data values of 74 and 187 and a mode of 87. Identify an additional value such that the resulting sample has a mean of 100 and a mode of 87. Additional value: A. Value: 152 B. Value: 87 C. Value: 8 D. Value: 65
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.

Mean and mode both try to measure the "central tendency" in a data set. The goal of each is to get an idea of a "typical" value in the data set.
- The average or Arithmetic Mean or mean of a given data is defined as :
- Mode is the observation that occurs most frequently in the data.
