HSCI 190 MODULE 1 CERTIFICATION
EVALUATION FULL QUESTION SET AND
VERIFIED SOLUTIONS
●● Research
Answer: Scientifically structured problem solving
●● Variable
Answer: Characteristics that change or can take on different values from
person to person
●● Categorical
Answer: A variable that can take on values that are names or labels of
data
●● Dichotomous
Answer: Variable that can take on one of only two possible values when
observed or measured
●● Discrete
Answer: Finite number of values, procedure establishes limit to number
of places one can take measure
,●● Continuous
Answer: Can take on any numerical value, can be infinite number, for
any two values of the measure, there is another value between them
●● Constant
Answer: Non-changing values; same for all participants
●● Statistics
Answer: Study of how to collect, organize, analyze, and interpret
numerical information from data
●● Population
Answer: Includes all elements from a set
●● Sample
Answer: Consists of one or more observations drawn from a population
●● Independent Variable
Answer: Used to examine their effects on another variable; what the
researcher is manipulating; often categorical with groups or levels
●● Dependent Variable
, Answer: Outcome or "effect" variable; measured in response to the
independent variable; usually measures effects; often continuous
●● Parameter
Answer: A numerical measure that describes a characteristic of an entire
population
●● Statistic
Answer: A numerical measure that describes a characteristic of sample
●● Nominal
Answer: 2 or more categories with no logical order
●● Interval
Answer: Has equal intervals with no absolute zero
●● Ordinal
Answer: 2 or more categories with a logical order
●● Ratio
Answer: Has equal intervals with an absolute zero
●● Sampling Error
