Statistics Unplugged--Chapter Notes (Introduction & Chapter 1)
î People use statistical analysis to carry out research and do it in a objective and
quantifiable way.
îWhen studying statistics you should allow yourself to become totally immersed in an
abstract
conceptual world, without any thought about direct applications
îIt is not that easy to get from point A to point B in statistics; it requires a lot of thought
and thinking.
Chapter One Notes
î Statistics can be used in a number of ways...
î A prison psychologist might collect info on levels of aggression in inmates,
while a
teacher might focus on their latest set of student test scores.
î Information may be collected on different variables
îVariable: Anything that can vary; it is anything that can take on
different quality or
quantities.
Eg: Age of students, attitudes towards a particular social issue, hours
spent
watching t.v, levels of pollution, ect.
îData Set: The collections, organization, and interpretation of data
according to well-defined
procedures.
îData Distributions: A listing of values or responses associated with a
particular variable in a
data set.
eg: Lets say you are looking at the age of 125 customers who enter a book
store. If you
list the age of each customer who entered (the 125 customers) in a columned
chart
then this would constitute as data distribution.
