Classify each of the following variables as either nominal or continuous. a. age b. gender c. height d. race Author’s Notes Multiple Choice Part (a) Options (correct choice comes first) Feedback (rejoinder) for this choice continuous Correct nominal Incorrect Multiple Choice Part (b) Options (correct choice comes first) Feedback (rejoinder) for this choice nominal Correct continuous Incorrect Multiple Choice Part (c) Options (correct choice comes first) Feedback (rejoinder) for this choice continuous Correct nominal Incorrect Multiple Choice Part (d) Options (correct choice comes first) Feedback (rejoinder) for this choice nominal Correct continuous Incorrect Exercise FieldStat4 1.MC.002. A café owner decided to calculate how much revenue he gained from lattes each month. What type of variable would the amount of revenue gained from lattes be? Author’s Notes Multiple Choice Options (correct choice comes first) Feedback (rejoinder) for this choice continuous Yes, the amount of revenue gained from lattes would be a continuous variable. A continuous variable is one for which, within the limits the variable ranges, any value is possible. Indeed, it is meaningful to speak of £107,543 (or dollars, euros etc.) (see Section 1.5.1.2). categorical This is incorrect because categorical variables are variables in which entities are divided into distinct categories (see Section 1.5.1.2). discrete This is incorrect because a discrete variable can only take on certain values (usually whole numbers) (see Section 1.5.1.2). nominal This is incorrect because a nominal variable is one that describes a name or category (see Section 1.5.1.2). Exercise FieldStat4 1.MC.003. A café owner wanted to compare how much revenue he gained from lattes across different months of the year. What type of variable is ‘month’? Author’s Notes Multiple Choice Options (correct choice comes first) Feedback (rejoinder) for this choice categorical Yes, this is correct because months of the year are divided into distinct categories (see Section 1.5.1.2). dependent This is incorrect because a ‘dependent variable’ represents the output or effect (see Section 1.5.1.1). Revenue would be the dependent variable. interval This is incorrect because interval variables can be measured along a continuum and they have a numerical value (for example, temperature measured in degrees Celsius or Fahrenheit) (see Section 1.5.1.2). continuous This is incorrect, a continuous variable is one for which within the limits the variable ranges, any value is possible (see Section 1.5.1.2).
