Industrial Statistics
Statistical analysis is a powerful tool for analyzing processes and product
performance. The subject can be intimidating, and for that reason do not
use statistics in assessing process control and manufacturing performance.
Industrial Statistics is presented from a nonstatistician's
perspective with an emphasis on how to use statistical concepts in a practical
manner.
Industrial Statistics is a 16-hour program that provides
participants with an in-depth understanding of how to:
-
Recognize and allow for the fundamental nature of variability.
-
Determine population means and standard deviations.
-
Develop a normal curve.
-
Recognize when distributions may not be normal.
-
Use statistical analysis to determine probabilities of occurrence
based on different statistical tests.
-
Use ANOVA techniques to determine if variance is due to randomness
or special causes.
-
Recognize when statistical process control might be an appropriate
process control technique.
-
Implement statistical process control.
