Explanation / Answer

Qualitative Data

Qualitative data arise when the observations fall into separate distinct categories.

Examples are:
Colour of eyes : blue, green, brown etc

Data are classified as:
nominal if there is no natural order between the categories (eg eye colour), or
ordinal if an ordering exists (eg exam results, socio-economic status).

Quantitative Data

Quantitative or numerical data arise when the observations are counts or measurements. The data are said to be discrete if the measurements are integers (eg number of people in a household, number of cigarettes smoked per day) and continuous if the measurements can take on any value, usually within some range (eg weight).

#1 Whether a gallon of milk is organic or regular---This is Qualitative and Nominal. OPTION D.

#2 The amount of milk produced by a particular cow in a day---This is Quantitative and Discrete. OPTION A.

#3 The number of cows on a farm---This is Quantitative. Now we can say that we can count the number of cows if it is a small number, then it becomes discrete, but in very large numbers, it becomes continuous, as then we can only take a range of values. Also this count is over a number of days. So the data is Quantitative and Continuous. OPTION A.

#4 The letter grade that students receive in a statistics course---This is a Qualitative data (eg A,B) , and since we can order them, they are Ordinal. The data would have been nominal if we had grades as pass/fail, but a letter grade can be used to compare between students based on grades. OPTION C.

#5 The heights of students in AMS 7L---These are Quantitative and Continuous. Option A.
