Data can be broken into: - correct answer ✔✔ qualitative and quantitative
qualitative data - correct answer ✔✔ Information describing color, odor, shape, or some other
physical characteristic; descriptive and conceptual and cannot be measured
Quantitative - correct answer ✔✔ relating to, measuring, or measured by the quantity of
something rather than its quality; can be counted, measured, and expressed using numbers
quatitative data can be split into: - correct answer ✔✔ numerical and categorical
numerical data - correct answer ✔✔ data is measured when continuous and counted when
discrete
numerical data can be split into: - correct answer ✔✔ interval and ratio
categorical data - correct answer ✔✔ Data that consists of names, labels, or other
nonnumerical values; contains a finite number of categories or distinct groups
categorical data can be spit into: - correct answer ✔✔ nominal and ordinal
categorical: nominal - correct answer ✔✔ -In nominal measurement the numerical values just
"name" the attribute uniquely; numbers can be used to classify or categorize
-you cannot add, average, median, etc w/ nominal data
categorical: ordinal - correct answer ✔✔ -Categorical data can be on an ordinal scale.
, -Numbers are used to indicate rank or order
-Relative magnitude of numbers is meaningful
-Differences between numbers are not comparable Example: Difference between strongly agree
and agree is not necessarily same as the difference between disagree and strongly disagree
-cannot add, multiply, or average
numerical: interval - correct answer ✔✔ -Also known as "Scale", "Quantitative" or "Parametric"
data
-Distances between consecutive integers are equal
-Relative magnitude of numbers is meaningful
-Differences between numbers are comparable
-Location of origin, "zero", is arbitrary (if the temperate reads 0 degrees that does not mean
there is no temperature
-data are always numerical
-cannnot multiple, divide, etc
numerical: ratio - correct answer ✔✔ -Ratio is very similar to the interval scale, with the
difference that it has a true zero point.
-This scale is commonly used for values that are measured in numbers, such as length, height,
weight, or monetary values like cost and revenue.
-Relative magnitude of numbers is meaningful
-Differences between numbers are comparable Location of origin, zero, is absolute (natural)
statistics is - correct answer ✔✔ the science concerned with developing and studying methods
for collecting, analyzing, interpreting and presenting empirical data to assist in making effective
decision.
Two types of statistics - correct answer ✔✔ descriptive and inferential
