a. Sketch a histogram showing the population distribution. b. locate the value of the popluation mean in your sketch, and make an estime of standard deviation ( as done in Example 4.2). C. Compute SS, variance, and standard deviation for the population. ( How well does your estimate compare with the actual value of v?)
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.
For the following population of N = 9 scores: 4, 2, 0, 5, 3, 2, 1, 7, 3
a. Sketch a histogram showing the population distribution.
b. locate the value of the popluation mean in your sketch, and make an estime of standard deviation ( as done in Example 4.2).
C. Compute SS, variance, and standard deviation for the population. ( How well does your estimate compare with the actual value of v?)
