Question

Classify the following data. Indicate whether the data is qualitative or quantitative, indicate whether the data is discrete, continuous, or neither, and indicate the level of measurement for the data.

1. Birth years of each person in your family.
a. Are these data qualitative or quantitative?
b. Are these data discrete or continuous?
c. What is the highest level of measurement the data possesses?

Answer 1

1.Quantitative

2.Discrete

3.Ratio Level of Management

Explanation:

1. Quantitative data is one which gives us the information about the quantity or number. Age is a number. Birth years are also numbers. So they are quantitative.

2. Discrete numbers are those numbers which include whole numbers and not fractions. Birth years cannot be expressed in fractions so they are not continuous they are discrete.

3. The highest level of measurement the data possesses is the Ratio Level. A ratio level can have a zero where as internal or ordinal cannot have. The nominal level does not have ordering. Age is ordered according to the birth years. Birth years are ordered according to numbers. Therefore it possesses the Ratio Level.

Answer 2

The data is quantitative, and discrete. The highest level of measurement of the data is Interval.

Explanation:

The birth years of people in my family are; 1965; 1969;1990, 1992 and 1997. This data is quantitative because it can be counted. Quantitative data is data that can be counted or measured whereas qualitative data can only be described.

The data is also a discrete data because they are round and concrete numbers. Discrete data can be obtained by just counting, whereas Continuous data can be obtained through measurement. Continuous data are more complex, Numbers like, 20.3, 19.1, are continuous.

The highest level of measurement the data possesses is Interval. The interval scale can be counted, subtracted, and have equal distances between them. However, they do not have a true zero and they do not indicate ratio.
