Find the mean, median, and mode of the data, if possible. If any of these measures cannot be found or a measure does not represent the center of the data, explain why. A sample of seven admission test scores for a professional school are listed below. 11.1 , 10.7 , 10.4 , 9.5 , 11 , 9.5 , 11.4 What is the mean score? Select the correct choice below and fill in any answer box to complete your choice. A. The mean score is= (Round to one decimal place as needed.) B. There is no mean score. What is the median score? Select the correct choice below and fill in any answer box to complete your choice. A. The median score is= (Round to one decimal place as needed.) B. There is no median score. What is the mode of the scores? Select the correct choice below and fill in any answer box to complete your choice. A. The mode(s) of the scores is (are)= (Use a comma to separate answers as needed.) B. There is no mode.
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.
