The box-and-whisker plot shows the yearly increase of population by hundreds in two towns during the last 20 years. Select all the true statements related to the box-and-whisker plots. Town A Town B 0 0.5 1 1.5 2 2.5 3 3.5 4 4.5 5 5.5 6 6.5 7 Amount of Increase (hundreds) O The range for both towns is the same. O The median amount of increase is greater for town A. O Town A has a greater interquartile range value than town B. O The interquartile range shows an annual growth for town A between 100 and 500 residents. O The interquartile range shows an annual growth for town B is between 200 and 600 residents.
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.
