The median home value in Pennsylvania and Massachusetts (adjusted for inflation) are shown below. Year Pennsylvania 42400 Massachusetts 1950 55400 2000 97000 185700 If we assume that the house values are changing linearly, a) In which state have home values increased at a higher rate? Select an answer b) If these trends were to continue, what would be the median home value in Pennsylvania in 2010? $4 Preview c) If we assume the linear trend existed before 1950 and continues after 2000, the two states' median house values will be (or were) equal in what year? (The answer might be absurd) The year Preview
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.
