The mean of the data set represented by the histogram is 12. What is a reasonable estimate for the median? Explain your reasoning. Select the correct answer below and, if necessary, fill in the answer box to complete your choice. (Type an integer or a decimal.) O A. The data are symmetrical and are centered about the mean, so the mean and median are about the same. The median is B. The median and the average are always the same. The median is C. The median cannot be obtained from the given information. D. The individual values can be obtained by multiplying the average and the frequencies. The median is Frequency
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.
