What are statistics? Statistics encompass the mathematical field that
allows us to organize, summarize, describe, and
interpret different forms of information.
Name 3 reasons why statistics are 1. Statistics allow data to be described and
important communicated succinctly and concisely.
2. Statistics allow inferences to be drawn about
data, particularly when it is not feasible to collect
information from all members of a certain group.
3. Statistics equip us with the necessary tools
needed to critically evaluate information.
Qualitative variables Variables measured in non-numerical terms, using
categories or labels
Quantitative variables Variables measured in numerical terms
Discrete variables Those that hold discrete values, such that they can
be organized into separate categories or counted
using whole numbers
, Continuous variables Variables that can theoretically be broken down
into infinitely smaller, fractional components
Name at least 3 examples of One's religion, ethnicity, eye color, and career
qualitative variables
Name at least 3 examples of Weight, height, heart rate, and test scores
quantitative variables
Describe the important variables The variable that is manipulated in an experiment is
involved in an experimental study known as the independent variable, and the
variable that is measured for any observable effect
is known as the dependent variable. A control
variable is a variable that remains unchanged
throughout the experiment. Extraneous, or
confounding, variables include any variables that
could unintentionally affect the dependent
variable.
Suppose you want to study the 1. Activity level: Dogs given more space and
