This class is not stats its social choice math but we're currently on the statistics portion. Our homework assignement asks for this... 1) Suppose you want to know if there is any association between soda consumption and obesity in children. Think about how you would go about organizing such a statistical study. What steps would you have to take/what items would you need to include in order to get it off the ground? Dont know where to even start or what kinds of steps. So far I only have this and im not sure if its correct: Set goal: to determine if there is any association between soda consumption and obesity. Randomly select 1,000 students from ages 7-13 in 4 Dade county schools (elementary and middle). ?
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.
