Identify the data set’s level of measurement. “The average daily temperature (in degrees Fahrenheit) on five randomly selected days 33,30,36,27,36
There are four levels of measurement.
- Nominal
- Ordinal
- Interval
- Ratio
The variables are divided into named groups without quantitative meaning is the nominal level of the measurement data set.
An example of a nominal scale is collecting data on the color of the pen the outcomes may be red, blue,etc which do not have mathematical meaning.
At the ordinal level, the variables are grouped into categories. Order is important
An example of an ordinal scale is product quality on a scale of 1 -3.
An interval scale is the numerical measurement of scale. The difference between the two variables is meaning full. It has an arbitrary zero.
An example of an interval scale is the IQ score of the students.
The ratio is also the quantitative level of measurement. It has a true zero.
An example of a ratio scale is the weight of a man in a bank.
Given that,
The average daily temperature (in degrees Fahrenheit) on five random selected days 33,36,36,27,36
