## Read the summary and the most important questions on Advanced Tools in quality management

• ### Basic statistics

This is a preview. There are 5 more flashcards available for chapter 04/01/2021

• #### What do terms populations and sample mean?

Population>(Random sampling)> Sample
• Why? To time consuming to stud whole population
• #### What are units and variables?

• Units: The elements of a sample from which we collect information.
• Example: Bottle
• Variable: measured property of an element of the sample
• Example: concertation of alcohol
• In general: the things we measure, like height, weight
• #### How can you discriminate the types of variables?

• Quantitative variable( continuous/discrete)
•  Height, percentage of alcohol( continuous)
• Number of children's in household(Discrete)
• Qualitative variable (nominal/ordinal)
• Hair colour, bachelor program (nominal)
• Grade of eggs (AA/A/B), highest level of education (ordinal)
• #### What are the different  probability distributions?

• One continuous distribution:
• normal
• Two discrete probability distributions:
• Binomial (n, p)
• Poisson
• #### What are general assumptions of Binomial situation?

• N trials
• The trials are independent
• Each trial result in ether success of failure
• The probability of succes, p remains the same each trial
• #### When Poisson distribution?

Calculate probability that a random batch has exact one complaint.
• ### General sampling principles

This is a preview. There are 12 more flashcards available for chapter 04/01/2021

• #### What are major quality control activities?

1. Measuring
2. Testing
3. Regulating
4. Taking corrective actions
• #### Why sampling in quality control?

• Variation in characteristic in food
• consist of biological material
• production involve human processes
• Sources of variation
• Common cause - Variation from natural sources or sources embedded in the system itself
• incidental causes - variaton arising from external sources: operator errors etc.
• Check if quality and safety parameters are within defined tolerances
• #### What is a sample ?

Is a subset from a large population or process.
• Is representative of the population
• Mirrors the characteristics of the population
• #### Why sampling incoming materials?

• Monitoring the quality of incoming materials
• Examining the number of defective products in batch of goods
• Crucial is control of process
