Which of the following statements is NOT TRUE regarding the calculating of the median of a data set. ___Before the median (or midpoint) of a data set can be determined, the quantitative data must be arranged in order (usually low to high). ___If there is an even number of members in the data set, there is no median. ___If there is an even number of members in the data set, the median is the average of the value just before and just after the midpoint.
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.
