Definition OC Curves or Operating Characteristic Curves refer to a graph of attributes of a sampling plan considered during management of a project which depicts the percent of lots or batches which are expected to be acceptable under the specified sampling plan and for a specified process quality. The specified sampling plan may be singular, sequential or iterative and may be using a particular size of a sample depending upon the demands of the project and could yield the results of acceptance or rejection based on a specified criteria. It helps in the selection of sampling plans It aids in the selection of plans that are effective in reducing risks. It can help in keeping the high cost of inspection low. There are two ways of calculating the OC curves. Binomial Distribution Poisson Formula Type A - Gives the probability of acceptance for an individual lot coming from finite production. Type B - Gives the probability of acceptance for lots coming from a continuous process. Type C - Gives the long-run percentage of product accepted during the sampling phase.

What does a bell curve of IQ look like?
The "bell curve" of anything, with the peak of the curve supposedly at a score of 100.
What is the definition of 'bell curve'?
A bell curve is a graph that depicts a large rounded peak tapering away at each end of normal distribution. A bell curve is a mathematical concept with the curve concentrated in the center.
Is the standard normal curve non symmetrical?
The standard normal curve is symmetrical.
Is it true that a normal distribution curve is symmetric about the mean?
yup, it's a bell curve
What are the properties of a standard normal curve?
It is a normal curve with mean = 0 and variance = 1.
