Which of following is NOT true about the standardization and z scores? O If you have az score of 0 on spelling test taken in your English class, it means that your test score is same with the average score. OZ scores tell researchers instantly how large or small an individual score is relative to other scores in the distribution. Standardization is simply the process of converting percentile scores in the distribution into standard deviations units. Through a process of standardization, researchers are better able to compare individual scores in the distributions of two separate variables.
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.
