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.

A new drug is being sold to treat anxiety, with a possible side effect being
hypercholesterolemia. Curious about this effect, a psychiatrist has his medical
technician do a blood draw from each of 6 high-anxiety patients at two times. The first
time is when treatment begins with a placebo condition (i.e., before taking the drug; not
to be confused with a placebo pill). The second time is after a month of taking the drug
on a regular schedule. The results of the cholesterol levels for all 6 patients at both
times are listed in the table above.
Question 1:
The participants from each level of the Independent Variable are from different groups.
A. True
B. False
Question 2:
In this example, the number of times blood was drawn is a binary variable.
A. True
B. False
