Measures of Variation include all of the following except
- A.
Median
- B.
Standard Deviation
- C.
Variance
- D.
Range
Correct Answer
A. MedianExplanation
Measures of variation are statistical tools used to describe the spread or dispersion of a data set. The median is not a measure of variation, but rather a measure of central tendency. It represents the middle value in a data set when it is arranged in ascending or descending order. In contrast, measures of variation such as standard deviation, variance, and range provide information about how spread out the data points are from the central value. Therefore, the median is not included in the measures of variation.Rate this question:
-

Two types of Variation are Common Cause and Special Cause
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The statement is true because common cause and special cause are indeed two types of variation in statistical process control. Common cause variation refers to the natural variation that is inherent in a process and is caused by factors that are consistently present. Special cause variation, on the other hand, is caused by factors that are not consistently present and can be attributed to specific events or circumstances. Understanding and distinguishing between these two types of variation is crucial in quality control and process improvement.Rate this question:

2 Types of Statisitics are Descriptive (Shape, Center, Variation) and Inferential (Hypothesis Testing)
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The statement is true because there are indeed two types of statistics: descriptive statistics and inferential statistics. Descriptive statistics involve summarizing and describing data through measures such as shape, center, and variation. On the other hand, inferential statistics involve making inferences and drawing conclusions about a population based on a sample, often through hypothesis testing. Therefore, the statement accurately describes the two main branches of statistics.Rate this question:
