Consider the preference schedule (below) for an election. ( c) A second election is held and candidate B drops out but voters do not change their preferences. Redraw the preference schedule with candidate B removed. (d) Find the winner of the preference schedule from (b) using the points method. First A B C Second B C A Third C A B Votes 11 7 5
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.
Consider the preference schedule (below) for an election.
( c) A second election is held and candidate B drops out but voters do not change their preferences. Redraw the preference schedule with candidate B removed.
(d) Find the winner of the preference schedule from (b) using the points method.
