Statistics chapter 1 definition
More types of calculations can be performed with data at the nominal level than with data at the interval level.
False. More types of calculations can be performed with data at the interval level than with data at the nominal level.
Quantitative data

The list of books that your friend read for school for the past five months is shown below.
Nominal. The data are categorized using names, labels, or qualities, but the data cannot be ranked or arranged in order
The jersey numbers for players on a basketball team are listed below.
Nominal. The data are categorized using numbers, but no mathematical computations can be made.
What is the level of measurement for "Pain level scale of 0 to 10 right parenthesis"?
Ordinal
Levels of measurement for which data can be quantitative
Ordinal, Interval, Ratio
Levels of measurement for which data can be qualitative
Ordinal, nominal
The regions of a country with the six longest life expectancy last year are shown below.
Qualitative. Ordinal.
Population of country or origin
Quantitative

Quantitative. Ratio
What is the level of measurement for "Age"?
Ratio
What is the level of measurement for "Time since last visit"?
Ratio
What is the level of measurement for "Weight"?
Ratio
The heights (in centimeters) of a sample of a species of plant 30 days after sprouting
Ratio. The data can be ordered and differences between data entries are meaningful, and a zero entry is an inherent zero.
Data at the ratio level cannot be put in order.
The statement is false. A true statement is "Data at the ratio level can be placed in a meaningful order."
For data at the interval level, you cannot calculate meaningful differences between data entries.
The statement is false. A true statement is "For data at the interval level, you can calculate meaningful differences between data entries."
Interval level
not only classifies and orders the measurements, but it also specifies that the distances between each interval on the scale are equivalent along the scale from low interval to high interval.
Select three examples of data sets that have inherent zeros below.
Average age of college students in years. Average monthly precipitation in inches. Maximum wind speed during a hurricane
Select three examples of data sets that do not have inherent zeros below.
Temperature in degrees Fahrenheit. A student's level of happiness measured from 0 to 10. Average IQ score of a high school class
Ordinal level
This level of measurement depicts some ordered relationship between the number of items.
What is an inherent zero?
a zero that implies none.
Qualitative data
information about the 'qualities' or characteristics of what is being studied. Can be descriptions, words, meanings, pictures, texts etc
Ratio level
the divisions between the points on the scale have an equivalent distance between them, and the rankings assigned to the items are according to their size.
Nominal level
the numbers are used to classify the data. Also, in this level of measurement, words and letters can be used.
