The Bureau of Elections in a county samples the voting records by party. It finds that the Yellow Party has a sample mean of 2,495 people who voted in the last election with a standard deviation of 34.65. The Orange Party has a sample mean of 2,575 and a standard deviation of 82.29. What inference can you make about the voter data? O The standard deviation for the Yellow Party data indicates that the range of people who voted is closer to the mean than for the Orange Party. O The standard deviation for the Orange Party data indicates that the range of people who voted is closer to the mean than for the Yellow Party. O The standard deviations and means for both parties indicate that more people in the Yellow Party voted than people in the Orange Party.
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.
