Use the distributions to answer the following question. set A set B 012 3 4 5 6 7 8 9 10 0123 45 6 7 8 9 10 Which of the following statements is TRUE about these distributions? O A. The standard deviation of setA is less than the standard deviation of set B, and their means are the same. O B. The mean of set A is less than the mean of set B, and the standard deviations are the same. O C. The standard deviation of set A is greater than the standard deviation of set B, and their means are the same. D. The mean of set A is greater than the mean of set B, and the standard deviations are the same.
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.
