Statistics Key Terms

3. The result of an experiment.
7. Values that possess names or labels.
9. The probability of an event occurring based upon other event probabilities.
12. To monitor and control a process so that the quality of the output/product improves.
13. The probability of satisfactory operation of the product in a given environment over a specified time interval.
14. Arithmetic average.
19. Listing of data values along with their corresponding frequencies.
23. A set of all possible outcomes or events in an experiment that cannot be further broken down.
27. An activity with observable results.
29. Categorical data graph.

1. The difference between the maximum and minimum dimensions allowed within the design of a product.
2. Measure of data scatter.
4. The square root of the variance.
5. Measure of variation equal to the sum of the deviations of each value from the mean.
6. The value that occurs most frequently.
8. SPC is a method of monitoring, controlling, and ideally improving a process through statistical analysis. Its four basic steps include measuring the process, eliminating variances in the process to make it consistent, monitoring the process, and improving the process to its best target value.
10. A subset of a sample space.
11. Bell-shaped probability distribution.
15. Categorical data graph %.
16. The use of quality control techniques associated with a process.
17. Frequency distribution graph.
18. Values that represent a measurable quantity.
20. Numbers or information describing some characteristic.
21. Frequency distribution graph.
22. Amount of difference between a value and the mean.
23. The collection, evaluation, and interpretation of data.
24. The calculated likelihood that a given event will occur.
25. Degree of conformity of a measure to a standard value.
26. The difference between samples.
28. Middle value of a set of values arranged in order of magnitude.
