General Terms
This is the set of all individuals of interest in a particular study.
What is the population.
What is parameter?
This is a method that allows us to study cause and effect by controlling variables.
What is experimental method?
This is a set of categories with no numerical identifiers. (Major, city of residence)
DAILY DOUBLE: Name the type of variable this is.`
What is nominal scale?
What is a discrete variable?
This letter is used for scores of a particular variable.
What is X?
A characteristic or condition that changes or has different values for different individuals.
What is a variable?
Statistical procedures used to summarize, organize, and simplify data.
What are descriptive statistics?
These are internal attributes or characteristics that cannot be directly observed but are useful for describing and explaining behavior.
What are constructs?
This variable consists of separate, indivisible categories. No values can exist between two neighboring categories.
What is a discrete variable?
This letter is used to identify the number of scores in a population.
What is N?
(Or big N)
These are measurements or observations.
What is data?
Usually a numeric value that describes a sample.
What is statistic?
Changes to the values of the variables to measure the effect on a second variable.
What is manipulation?
These are categories organized in order. (Birth order – oldest, middle, youngest)
What are ordinal scales?
This letter is used to identify the number of scores in a sample.
What is n?
(Or lowercase n)
The set of individuals selected from a population, usually intended to represent the population in a research study.
What is sample?
This method is when two different variables are observed to determine whether there is a relationship between them.
What is the correlational method?
These are variables that should not influence the outcome of an experiment.
What is control?
Zero is an absence of the variable (number of study hours. Cannot have negative hours.)
What is ratio scale?
This Greek letter is used to stand for summation.
What is Σ?
(or Sigma)
The natural occurring discrepancy that exists between a sample statistic and the corresponding population parameter.
What is sampling error?
This consists of techniques that allow us to study samples and then make generalizations about the populations from which the samples were selected.
What is inferential statistics?
Another possible explanation for the result of an experiment.
What is a confound?
Zero does not mean the absence of that variable. (Temperature, goes below zero. Difference from mean)
DAILY DOUBLE 2: Name this type of variable.
What is interval scale?
What is a continuous variable?
This letter is used for the number of times a score appears.
What is f?
(or lowercase f for frequency)
