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 tw…

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 o…

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 compar…

b. ln light of part (a), does representation increase or decrease in moving to the right on the graph?

c. Describe the overall trend in the data. In general, does federal aid increase or decrease with representation?

d. Describe the correlation (if any) in the data in terrns of strong/weak and positive/negative.

e. Do you believe the correlation between representation and federal aid is more likely a coincidence, due to a common underlying cause, or due to a causal relationship? Explain.
