variable
an attribute that varies, having at least two levels, or values. See also, dependent variable, independent variable, manipulated variable, measured variable
constant
an attribute that could potentially vary but that has only one level in the study in question
levels
one of the possible variations, or values, of a variable
measured variable
a variable in an experiment whose levels (values) are observed and recorded. (See also, manipulated variable)
manipulated variable
a variable in an experiment that a researcher controls, such as by assigning participants to its different levels (values). (see also, measured variable)
conceptual variables
a variable of interest, stated at an abstract, or conversational, level. aka construct (see also, conceptual definition)
construct
a variable of interest, stated at an abstract level, usually defined as part of a formal statement of a psychological theory. (see also conceptual variable)
conceptual definitions
a researcher's definition of a variable at the theoretical level. aka construct (see also, conceptual variable)
operational definitions
the specific way in which a concept of interest is measured or manipulated as a variable in a study.
aka operationalization or operational variable
operational variables
the specific way in which a concept of interest is measured or manipulated as a variable in a study.
operationalize
to turn a conceptual definition of a variable into a specific measured variable or manipulated variable in order to conduct a research study
experiment
in psychology, specifically means that the researchers manipulated at least one variable and measured another
independent variable
a variable that is manipulated in an experiment
conditions
one of the levels of the independent variable in an experiment
dependent variable
in an experiment, the variable that is measured.
control variable
a potential variable that an experimenter holds constant on purpose
comparison group
a group in an experiment whose level on the independent variable differs from those of the treatment group in some intended and meaningful way. aka comparison condition
control group
a level of an independent variable tha is intended to represent "no treatment" or a neutral condition
treatment group(s)
the participants in an experiment who are exposed to the level of the independent variable that involves a medication, therapy, or intervention
placebo group
a control group that is exposed to an inert treatment (eg sugar pill) aka placebo control group
confounds
a general term for a potential alternative explanation for a research finding ( a threat to internal validity)
descriptive statistics
a set of statistics used to organize and summarize the properties of a set of data
data matrix
a grid presenting collected data
frequency distribution
A table showing how many of the cases in a batch of data scored each possible value or range of values on the variable
frequency histogram
a graph showing how many of the cases in a batch of data scored each possible value or range of values on the variable
stemplot
a graphical representation of the values obtained on some variable in a sample of data. aka stem and leaf plot
central tendency
a value that the individual scores in a data set tend to center on (see also, mean, median, mode)
mode
a measure of central tendency that is the most common score in a set of data
bimodal
having 2 modes, or most common scores
multimodal
having two or more modes, or most common scores
median
a measure of central tendency that is the value at the middlemost score of a distribution of scores, dividing the frequency distribution into halves
mean
an arithmethic average; a measure of central tendency computed from the sum of all scores in a set of data, divided by the total number of scores
variance
a computation that quantifies how spread out the scores of a sample are around their mean; it is the square of the standard deviation
standard deviation
a computation that captures how far, on average, each score in a data set is from the mean
z score
a computation that describes how far an individual score is above or below the mean, in standard deviation units. aka standardized score

ECONOMICS
Pension funds pay lifetime annuities to recipients. If a firm remains in business indefinitely, the pension obligation will resemble a perpetuity. Suppose, therefore, that you are managing a pension fund with obligations to make perpetual payments of $2 million per year to beneficiaries. The yield to maturity on all bonds is 16%. What will be the par value of your holdings in the 20-year coupon bond?
