We perform a regression analysis on a pair of
variables and determine that there is a linear
relationship. The regression line is determined to be
y=12x−5y=12x-5. What type of linear relationship
exists between the independent variable, x, and the
dependent variable, y? - ANSWER-positive
describe R-squared? - ANSWER-a) R-squared
measures the goodness of fit.
b) R-squared can be misleading if there are false
independent variables.
c) R-squared is 1.0 when correlation is -1 or 1.
,Which of the following are technique a manager
uses when forecasting? - ANSWER-A)Time Series
c) Associative
d) Judgmental
Percentile - ANSWER-The value at which a certain
percentage of the sample or population fall below
combination - ANSWER-The number of different
unordered possibilities for a certain situation
Probability - ANSWER-The chance of an event
occurring
Histogram - ANSWER-A graph that displays
continuous data. This type of graph has vertical bars
that show the counts or numbers in each range of
data.
Which of the following are advantages of cluster
analysis? - ANSWER-b) It sorts individual data
points into different groups.
c) It will not help in determining target markets.
d) It does not identify successful and unsuccessful
habits and systems.
,A trend is... - ANSWER-a general slope upward or
downward over a long period of time.
If there is a relationship between variables, but the
relationship is not linear, what possible challenge
with regression could it be? - ANSWER-Polynomial
Regression
Catherine is trying to sell a ticket to the Super Bowl.
She is determining whether or not she should sell a
ticket now or wait until just before the game and try
and sell it then. Currently, someone is offering $350
for the ticket. From research of past prices, she
knows that the tickets immediately before the Super
Bowl are sold for about $500. She determines that
there is a 75 percent chance she will be able to sell
the ticket immediately before the Super Bowl. Based
on expected payoffs from risk decision making, what
should she do? How much is the difference if she
chooses to sell now - ANSWER-Catherine should
wait to sell ticket; the difference will be $25.
Heteroscedasticity - ANSWER-A regression in which
the variances in y for the values of x are not equal
Cumulative Average-Time Learning Model -
ANSWER-A learning curve model in which the
cumulative average time per unit declines by a
, constant percentage each time the cumulative
quantity of units produced is doubled
Dependent Variable - ANSWER-The variable whose
value depends on one or more variables in the
equation; typically the cost or activity to be predicted
Independent Variable - ANSWER-The variable
presumed to influence another variable (dependent
variable); typically it is the level of activity or cost
driver
Analysis of Variance (ANOVA) - ANSWER-A
statistical method that helps identify the sources of
variability by comparing their means or averages; it
compares the variation within a sample to the
variation between samples to see if any differences
are the result of some contributing factor or if the
differences occur by chance alon
Experience Curve - ANSWER-A curve that shows
the decline in cost per unit in various business
functions of the value chain as the amount of these
activities increases
Crossover Analysis - ANSWER-Allows a decision
maker to identify the crossover point, which
