Exam 14: Statistical Process Control

Samples gathered in such a way that every piece of product has an equal chance of being selected for inspection are called systematic samples.

A measurement to determine if a defect is either present or not is known as an attribute.

The control chart used to count the number nonconforming in a consistent sample space is called the

A continuous measurement such as weight,height,or volume is known as

On a control chart,two data points near the UCL requires an investigation for the cause of variation,however two data points near the LCL does not call for any investigation and is part of normal behavior.

On a control chart,how many successive data points on an increasing or decreasing line require an investigation for cause of progressive change?

The control chart used to monitor the average of the characteristic being measured is called a(n)________ chart.

Variation that centers on a mean and occurs with a somewhat consistent amount of dispersion is known as ________ variation.

The jump in sales of hand sanitizers experienced by the manufacturer of sanitizing products due to a scare of H1N1 virus outbreak is known as ________ variation.

Five points in sequence,either above or below the mean are called ________.

A process which is in control is always a capable process.

Seven points in succession,all increasing or decreasing in a process chart are called ________.

Variation that results from a specific event,which may be a shift in a process mean or an unexpected occurrence,is known as ________ variation.

Use the information below to answer the following question(s).Use the "Factors for Control Limits" Table A.3 from the textbook where required: A control chart needs to be developed to determine if the temperature for a process is within control limits.Five samples each having 4 observations are taken and the sample measurements (temperature in degrees F)are noted in the table below: -What is the LCL for a X-bar chart?

The control chart used to measure the proportion defective is called the

Use the information below to answer the following question(s).Use the "Factors for Control Limits" Table A.3 from the textbook where required: A control chart needs to be developed to determine if the temperature for a process is within control limits.Five samples each having 4 observations are taken and the sample measurements (temperature in degrees F)are noted in the table below: -What is the value of the grand mean?

Variation that results from a specific event,which may be a shift in a process mean or an unexpected occurrence,is known as random variation.

A process that is stable has no variation present in the process.

Concluding that a process is stable means only ________ variation is present in the process.

Use the information below to answer the following question(s). An inspector visually inspects 10 samples of 200 computer monitors each for defects.Using trained judgement,the inspector either accepts or rejects the monitors based on whether they are flawless.The table below gives the results of these inspections from the 10 samples: -What is the LCL for a p chart?
