Question
Come up with a quantitative variable Identify the appropriate scale of measurement. Identify whether this variable is discrete or continuous (or at least theoretically continuous). Identify all of the frequency distribution graphs that would be appropriate for this variable. Come up with a qualitative variable (not mentioned in the text). Identify the appropriate scale of measurement. Identify whether this variable is discrete or continuous (or at least theoretically continuous). Identify all of the frequency distribution graphs that would be appropriate for this variable. Come up with one example of when it would be better to use a quantitative variable. Come up with one example of when it would be better to use a qualitative variable.
Explanation / Answer
Quantitative variables are the variables that can be counted such as number of fishes in the pond,number of students in the class, temperature of room etc.
let us consider the temperature of room is 20 degrees ( a quantitave variable) ,
hence scale of measurement would be INTERVAL SCALE,and they don’t have a “true zero.” For example, there is no such thing as “no temperature",which makes this scale different from RATIO SCALE (which can be divided though or can be expressed in terms of ratio), adding further in case of interval scale it is like-(we cannt say that 40 degree temperature is twice hot as compared with 20 degree temperature.
Temperature is continuous as it can be any real number.
Histrogram is appropriate for continuous data.
Qualitative variable is used better when we needed to describe qualities such as excellence,beauty,nature etc.
