In this video, Dr. Richard Chua explains when to select, develop, and use chi-square contingency tables during a Six Sigma project.
- If your Grandmother needs to undergo a particular surgery…and there are four hospitals in the local area,…doesn't matter which hospital performs the surgery,…before you decide you will need to determine if…the outcome is independent of or dependent on…the choice of hospital.…To do this, let's take a look at the Chi-Square test,…using Contingency Tables.…So let's say these are the four hospitals…that perform the particular surgery that Grandma needs.…This is the most recent data from the past 12 months.…
The possible outcomes are full recovery,…partial recovery, and death.…Based on this data, is the outcome independent of hospital…or is the outcome dependent on hospital?…The appropriate hypophysis test for this,…is the Chi-Square test for association.…Also called the test for independence.…In general, the now hypothesis is outcome y,…is independent of factor x.…And the alternate is, outcome y is not independent.…
In other words, it is dependent on factor x.…In our example, the surgical outcome is…independent of hospital.…
