The difference between the highest value and the lowest value in the data set is
known as the:
*Breadth.
*Range.
*Standard deviation.
*IQ range.

Range = Maximum - minimum
T/F Measurement error is the difference between the actual value of a characteristic
being measured and the value obtained by the measurement system.

, True
Measurement error is defined as the effect of all sources of measurement
variability that caused an observed or measured value to deviate from the
true value.
Which of the followings summarizes data about the shape, dispersion, and center of
the data?
*SIPOC
*Multi-vari chart
*Box plot
*Pareto chart

Box plot
A box plot summarizes data about the shape, dispersion, and center of the
data graphically.
Which control chart is used for rejection data with the same number of units in each
sample?
*P chart
*U chart
*Np chart
*C chart

, NP Chart
The np control chart is used for discrete data when we want to plot
defective/rejection data with a constant sample size.
During a hypothesis test, a Six Sigma team lead discovered that the null hypothesis
was not rejected when a difference between the means existed. What type of error
occurred?
*Type 2
*Mistake
*Type 1
*Alpha
Give this one a try later!
Type 2
A type 2 error indicates failing to reject the null hypothesis when a
difference exists. On the contrary, a type 1 or alpha error indicates rejecting
the null hypothesis when in reality it is true (i.e., there is no difference).
T/F The company XYZ Co. deals in flashlight manufacturing and exports to three major
countries. In business unit A of XYZ, there are too many flashlight returns, and
flashlight sales have decreased by 25%. This is an example of a business case.

, True
The business case is a high-level articulation of the area of concern. This
case answers two primary questions: What is the business motivation for
considering the project? And what is our general area of focus for the
improvement effort?
Which element of waste best describes the unnecessary movement of materials,
products, and/or services?
*Overprocessing
*Motion
*Transport
*Waiting

Transport
The unnecessary movement of goods, services, and/or products from one
place to another is called transport waste. This typically involves using a
forklift truck or smaller similar equipment to maneuver products around the
factory. The situation is typically caused by overproduction and inefficient
building layouts.
Below is the multi-vari chart to study the variation in metal strength due to metal type
(15/18/21) and heating time (hours.). What should you conclude?
Metal 15: 30 min 21.4, 1 HR 20.3, 1.5 HR 17.2
Metal 18: 30 min 20.2, 1 HR 24, 1.5 HR 21.3
Metal 21: 30 min 19.2, 1 HR 20.3, 1.5 HR 22
A) There is no interaction between metal type and time.
B) Metal 15 shows a lot of variation for different time values.
