DISCOVERING STATISTICS FINAL PAPER
GRADED A PLUS VERIFIED QUESTIONS
WITH FULL SOLUTION
●● Between-Group design
Answer: Another name for independent design.
●● Between-subject design
Answer: Another name for independent design.
●● Bimodal
Answer: a description of a distribution of observations that has two
modes.
●● Binary variable
Answer: a categorical variable that has only two mutually exclusive
categories (dead or alive).
●● Boredom effect
Answer: refers to the possibility that performance in tasks may be
influenced (assumed negative) by boredom/lack of concentration if there
are many tasks, or the task goes on for a long period of time.
, ●● Categorical variable
Answer: any variable made up of categories of objects/entities.The UK
degree classifications are a good example because degrees are classified
as a 1, 2:1,2:2,3, pass or fail. Therefore, graduates form a categorical
variable because they will fall into only one of these categories.
●● Central tendency
Answer: a generic term describing the centre of a frequency distribution
of observations as measured by the mean, mode and median.
●● Confounding variable
Answer: a variable (that we may or may not have measured) other than
the predictor variables in which we're interested that potentially affects
an outcome variable.
●● Correlational research
Answer: a form of research in which you observe what naturally goes on
in the world without directly interfering with it. This term implies that
data will be will be analyzed so as to look at relationships between
naturally-occuring variables rather than making statements about cause
and effect. Compare with cross-sectional research and experimental
research.
