Statistics Modeling and Finance QUESTIONS
AND ANSWERS 100% CORRECT
Opinion Correct answera view, judgment, or appraisal formed in the mind about a
particular matter.
descriptive statistics Correct answerA branch of statistics concerned only with
characterizing, or describing, a set of numbers. The measures used to characterize a
set of data (e.g., average, maximum, coefficient of dispersion) or charts and tables
depicting the data.
inferential statistics Correct answerThe process of drawing conclusions about
population characteristics through analysis of sample data.
graph Correct answerA chart or visual representation of data relying on references
to two axes, which may be either numerical or categorical in scale. For example, a
scatter plot is a graph referencing two numerically scaled axes, whereas a bar chart
is a graph referencing one numerical axis and one categorical axis.
Graphic analysis Correct answerQuantitative techniques used to identify and
measure adjustments to the sale prices of comparable properties; a variant of
statistical analysis in which an appraiser interprets graphically displayed data
visually or through curve fit analysis. Graphs can also be used to support and
exhibit value trends for comparison elements in qualitative analysis.
variable Correct answerIn statistics, a characteristic or attribute of an item, service,
or individual that can change from observation to observation. For example,
improved living area is a characteristic of a house that can change with each
observation.
dependent variable Correct answerThe variable being estimated (outcome or
response variable) in a predictive model such as a multiple linear regression
equation.
Trend Correct answerA series of related changes brought about by a chain of
causes and effects. Trends are forecast through economic base analysis, statistical
analysis, market analysis, and analysis of economic indicators and surveys.
,Random Relationship Correct answerSometimes variables are not related. There is
no causal effect exerted by the independent variable on the dependent variable.
A scatter diagram will also reveal if there is no relationship.
Negative Relationship Correct answerScatter diagrams can also record negative
relationships. We said that a positive correlation trends up and to the right. A
negative relationship moves up and towards the left. That would mean a higher
amount of one variable would lead to a lower price in the other variable.
Your stock went from $125 to $97.25 in three years. What is the average percent
change per year? Correct answer-7.4%
"Quantitative techniques used to identify and measure adjustments to the sale
prices of comparable properties; a variant of statistical analysis in which an

analysis" is the definition of _____________ analysis. Correct answerGraphic

answergraph
A(n) _______________ is defined as "a characteristic or attribute of an item,
service, or individual that can change from observation to observation." Correct
answervariable
"The process of drawing conclusions about population characteristics through
analysis of sample data" defines ___________ statistics. Correct answerinferential
All the charts and graphs in the course were prepared using Correct
answerMicrosoft Excel
Central tendency Correct answerThe central point, or representative value, around
which items cluster in a frequency distribution. The measures of central tendency
(called averages) are the mean, the median, and the mode.
mean Correct answerA measure of central tendency. The sum of values for a
variable in a sample or population divided by the number of items in the sample or
population. The arithmetic average.
, Universe Correct answerIn statistics, a population or entire body of data; used to
distinguish between a population and a sample obtained from the population.
Population is a more generally used term.
Sample Correct answerIn statistics, a subset of a population selected for analysis.
parameter Correct answer1. A constant or value used to index a function, such as
use of degrees of freedom to derive an appropriate t-statistic or F-statistic function.
Aggregate Correct answerThe sum of all the observations within a population; e.g.,
the aggregate sale price of all the houses sold in a given community.
median Correct answermeasure of central tendency identified as the middle value
in an ordered array of numerical values
mode Correct answerA measure of central tendency consisting of the numerical
value or categorical characteristic that occurs most frequently in a sample or
population.
The ________ is most affected by extreme values. Correct answermean
The _______ describes the central position in an array. Correct answermedian
Central tendency is part of ________________ statistics. Correct
