Sample size for Confidence Intervals and Hypothesis Testing for making Inferences

BIS.Net Team BIS.Net Team

There are two alternatives with regards to sample size for inferences. One alternative is to take a sample size considered to be economical and practical, or as dictated by circumstances.

Information Overload

The BIS.Net Team The BIS.Net Team

Analysis is about converting data into information to help make decisions. But how much information do we need? This article concerns the problem of information overload.

Complexity versus Simplicity, Confusion versus Contribution, Impressive versus Knowledge and Understanding

The BIS.Net Team The BIS.Net Team

Academia has also fallen into the trap of overcomplicating. Of course, academic thinking is at a higher than normal level of thinking, at a level of complexity that the average person will not understand.

About Measurement System Analysis

The BIS.Net Team The BIS.Net Team

No measuring device is perfect. There will always be a small amount of error, some due to faults and imperfections with the equipment, some due to robustness problems with ambient conditions, some due to inadequate training, and many other reasons.

Acceptance Sampling

The BIS.Net Team The BIS.Net Team

There has been considerable controversy over the use and benefits of Acceptance Sampling. The objective of this small article is to provide a balanced perspective for practitioners to decide for themselves whether to apply or not apply acceptance sampling as an additional form of quality protection.

Robustness of Distribution Optimized X-Bar Charts (or How and why a standard X-bar chart can fail with perfectly normal data)

Dr Juergen Ude Dr Juergen Ude

So how can normally distributed data be so much out of control? The individual data is normal, the sampling distribution is normal.

About Change Analysis - A modern alternative to Shewhart Control Charts

Dr Juergen Ude Dr Juergen Ude

Change Analysis is used to detect changes in chronological ordered data. Using machine power algorithms, combined with statistical significance testing, changes in the process average, standard deviation and slopes can be rapidly detected.

Machine-Learning

Dr Juergen Ude Dr Juergen Ude

Machine learning has recently become popular to the extent that it has received a somewhat mythical status, as is the norm with the latest ‘fads’. Historically there have been many ‘fads’ of which, TQM, Kaizen, JIT, 6 Sigma, Analytics, AI are some examples.

Machine Power and Fuzzy Decision making applied to Surveys

Dr Juergen Ude Dr Juergen Ude

Considerable academic research has been performed on Survey Analysis, under the topics of Categorial Analysis and Contingency Tables. Much of the technology originated between 50 to 300 years ago and can be considered out-of-date.
