Question

Indicate whether each variable is (1) continuous or (2) discrete.

a) Age measured in years
b) Political Party (Democrat, Republican, or other)
c) How many bottle/cans of beer if any do you drink in a typical week?
d) Weight measured in pounds
e) Height measured in inches
f) On a scale form 1 (strongly disagree) to 7 (strongly agree), how nervous and uneasy do you feel about taking this statistics class?
g) Are you currently in a serious romantic relationship? (Yes or No)
h) The number of hours you spend on the internet
i)Age measured in years

Answer 1

The variables have been classified as either continuous, discrete, qualitative/categorical, or ordinal based on whether they represent countable numbers, measurable quantities, categorical choices, or ranked levels.

Step-by-step explanation:

Indicating whether each variable is continuous or discrete involves determining whether the data can take on any value within a range (continuous) or if they can only take on specific values (discrete). Let's analyze the given variables:

• Age measured in years is generally considered discrete because it is counted in whole years.
• Political Party is qualitative or categorical and therefore neither continuous nor discrete as quantitative terms.
• Number of bottle/cans of beer is a quantitative discrete variable because you count the number of cans/bottles.
• Weight measured in pounds is a continuous variable since weight can be measured with high precision and can take on any value within a range.
• Height measured in inches is also considered continuous for the same reason as weight.
• Scale from 1 to 7 about nervousness for statistics class is ordinal, which is neither continuous nor discrete as quantitative terms but a qualitative measure since it involves ranking.
• Being in a serious romantic relationship is a categorical data type since it’s a yes or no question.
• Number of hours spent on the internet can be considered continuous if you consider fractional hours, if it is only full hours, then it would be discrete.
• Age measured in years (repeated) is again discrete.
