For this particular data set could Month and Day be consider

For this particular data set, could ”Month” and ”Day” be considered ordered factors rather than numeric variables?

A data frame with 154 observations on 6 variables. (,1 J Ozone numeric Ozone (ppb) [,2 J Solar. R numeric Solar R (lang) [,3 J Wind numeric Wind (mph) (,4J Temp numeric Temperature (degrees F) [,5 J Month numeric Month (1-12) (,6] Day numeric Day of month (1-31) Details Daily readings of the following air quality values for May 1, 1973 (a Tuesday) to September 30, 1973. . Ozone: Mean ozone in parts per billion from 1300 to 1500 hours at Roosevelt Island . Solar.R: Solar radiation in Langleys in the frequency band 4000?7700 Angstroms from 0800 to 1200 hours at Central Park . Wind: Average wind speed in miles per hour at 0700 and 1000 hours at LaGuardia Airport . Temp: Maximum daily temperature in degrees Fahrenheit at La Guardia Airport.

Solution

Yes.

Why?

We set an example. If we compare January 17 and January 18, the \"18\" does not signify a larger quantity than the \"17\", but simply a number being next to 17.

The same goes for month.

Thus, month and day can be considered ordered factors, rather than numeric variables.
