MGSC 485 Final TEST Questions And
CORRECT Answers
basic/simple checksheet - CORRECT ANSWERS most basic form of data collection.
tally up numbers and total them.
frequency plot checksheet - CORRECT ANSWERS appropriate when identifying probabilities of
different types of customer concerns about a product/service
traveler checksheet - CORRECT ANSWERS this type of checksheet follows the patient through
the cycle, timing each step to see how long it takes
it is a full cycle observation
appropriate when finding out process times and total process flow time for a patient in a hospital
location checksheet - CORRECT ANSWERS are all items in the location that provides highest
efficiency?
appropriate when:
identifying the areas of a computer work station that are most damaged during production
identify problems with positioning of fields on an insurance claim form that had let to complete
response on critical items
continuous data - CORRECT ANSWERS measured on a continuous scale
can be infinitely divided
examples: time, cost, physical dimensions
,continuous - interval data - CORRECT ANSWERS real number (value)
no zero basis (zero not defined)
example: temperature, humidity
continuous - ratio scale data - CORRECT ANSWERS real number (value)
has a zero basis (zero IS defined)
example: height, weight, distance
attribute - count data - CORRECT ANSWERS discrete values (counts)
example: count of absent students, number of defects per table
attribute - binary data - CORRECT ANSWERS two discrete/integer values (0, 1)
examples:
green belt/no green belt
male or female
yes or no
pass or fail
attribute - nominal data - CORRECT ANSWERS many discrete values
*no hierarchy*
categories/labels
, All equal, not one higher than the other, cannot be ranked
example: departments in school (marketing, finance, accounting, etc.)
calculating sample size for continuous data - CORRECT ANSWERS use the sample size formula
given
standard deviation of the entire process equals the SD of each step squared (variance), add them
together and take the square root
when only a range is available (no SD), you calculate the range and DIVIDE BY 4. Use this number in
the formula as the standard deviation.
attribute - ordinal data - CORRECT ANSWERS many discrete values
categories/labels
*hierarchy*
CAN be ranked
example: customer satisfaction ratings, military offers ranking
calculating sample size for discrete data - CORRECT ANSWERS when you aren't given any actual
data
descriptive statistics - CORRECT ANSWERS represent a characteristic of a large group of
observations (a population or a sample representing a population)
mean and standard deviation
inferential statistics - CORRECT ANSWERS draw conclusions about a population based upon
analysis of sample data
