Subjects (just one word): Observations (just one word): Factor: Type of singer Number of Levels (a number): How many bass singers were observed? What was the total height of the tenor singers? What was the average height of the alto singers (to one decimal place)? What was the variance of the soprano singers’ heights (to one decimal place)? What was the standard deviation of the bass singers’ heights (to one decimal place)? How many singers altogether were observed? The output contains two estimates of the common population variance: Which of the two estimates is expected to be stable (to one decimal place)? Which of the two estimates is expected to change as the population means change (to one decimal place)?
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.

Factor: Type of singer
Number of Levels (a number):
How many bass singers were observed?
What was the total height of the tenor singers?
What was the average height of the alto singers (to one decimal place)?
What was the variance of the soprano singers’ heights (to one decimal place)?
What was the standard deviation of the bass singers’ heights (to one decimal place)?
