The member will learn the types of data, graphs and their applications in six sigma projects
- Throughout this chapter,…we have been using the example of a pizza chain…with customer complaints about their crust.…Let's return to our example…to help us understand the types of data and graphs used…in Six Sigma projects.…With a pizza crust problem, you would want to know…if the thickness of pizza crust is consistent…and how many complaints on pizza crust were received…by each of the 10 restaurants.…There are two types of data, continuous and discrete.…Knowing the type of data can help you determine…which graphs to use.…
Continuous data is data that can take on any value…on a continuum or continuous scale,…such as inches or centimeters on a measuring tape,…or pounds or kilograms on a weighing scale.…Continuous data can be expressed as decimals or fractions,…such as 2.2 meters tall,…or weighing 175.6 pounds.…Discrete data is data that take on values…which are integers or whole numbers.…In other words, discrete values.…
These are usually numbers that you can count.…Examples include number of complaints,…number of people in each checkout line,…
