What analyses and interprets data in relation to samples and populations? -
ANSWER: Statistics
What can help to determine how much of an observed change occurred as a result
of something or just by chance? - ANSWER: Statistics
A population characteristic - ANSWER: Parameter
A numerical value that represents a sample characteristic - ANSWER: Statistic
Anything that is being observed or measured - ANSWER: Variable
The intervention, or what is being manipulated - ANSWER: Independent variable
The outcome of interest; should change in response to intervention - ANSWER:
Dependent variable
Something that is out of the examiners control and can possibly affect the validity of
the researchers results - ANSWER: Extraneous variable
Variables can also be referred to as what? - ANSWER: Data
What are the 2 types of data? - ANSWER: 1. Categorical
2. Continuous
A type of data that is a limited set of values, and if expressed in numerical form then
ONLY whole numbers - ANSWER: Categorical
A type of data that takes any value within defined range (therefore does not have to
be whole #s)? - ANSWER: Continuous
Is the following examples of categorical or continuous data?
gender, number of decayed, missing, filled teeth, 1 or 2 children - ANSWER:
Categorical
Is the following examples of categorical or continuous data?
blood pressure, height, weight, time, age - ANSWER: Continuous
, What are the 2 scales of categorical data? - ANSWER: Nominal scales and Ordinal
scales
What are the 2 scales of continuous data? - ANSWER: Interval and ratio scales
What kind of scale is named categories? And what kind of data is this? - ANSWER:
Nominal scales, which is categorical data
What kind of scale ranks items in order (high to low, or low to high)? And what kind
of data is this? - ANSWER: Ordinal scales, which is categorical data
True or false:
nominal and ordinal scales (both categorical data) both have a mathematical
relationship - ANSWER: False!
neither one has a mathematical relationship
True or false:
Ordinal scales are an indication of how much higher or lower one item is in relation
to another - ANSWER: False!
They are NOT an indication as they are subjective (NO mathematical relationship)
What kind of scale has equal intervals between values and NO true 0 point (that
indicates the absence of something)? And what kind of data is this? - ANSWER:
Interval scale, which is continuous data
What kind of scale has intervals between values that are consistent and meaningful,
and has a true 0 point (= complete absence of the attribute being measured) -
ANSWER: Ratio scale, which is continuous data
The following are some examples of what kind of scale?
pain scale of 1-10 (1 is no pain to 10 is severe pain) and Stages of Cancer - ANSWER:
Ordinal scales
The following are some examples of what kind of scale?
gender, eye color, yes/no - ANSWER: Nominal scales
The following is a example of what kind of scale?
temperature - ANSWER: Interval scale
The following are some examples of what kind of scale?
