The number of credits being taken by a sample of 13 full-time college students are listed below. Find the mean, median measure cannot be found or does not represent the center of the data, explain why. 8 8 11 11 8 9777777 10 O Find the median. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. O A. The median is (Type an integer or decimal rounded to one decimal place as needed.) O B. The data set does not have a median. Does the median represent the center of the data? O A. The median represents the center. O B. The median does not represent the center because it is the smallest data value. O C. The median does not represent the center because it is not a data value. O D. The median does not represent the center because it is the largest data value. O E. The data set does not have a median.
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.
