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.
Refer to the p chart in Section 8.2 Exercise 10 of the text.
According to this p chart, is the process within statistical control? If not, provide a reason why not.
| a. | It does not appear to be within statistical control because at least one point is more extreme than the UCL or LCL. | b. | It appears to be within statistical control. |
|---|---|---|---|
| c. | It does not appear to be within statistical control because there is an obvious non-random trend, cycle, or pattern in the points. | d. | It does not appear to be within statistical control because at least 8 consecutive points are located all above or all below the centerline |
