Question

an appliance store sells microwave ovens and has many different styles to choose from. a handout from the store contains details about brand, type (countertop or over - range), number of power settings, and color. which of the variables is a discrete quantitative variable? brand type power settings color

Explanation:

• Brand: It is a qualitative variable as it represents different names or labels (e.g., Samsung, LG) without any numerical value associated with it in a quantitative sense.
• Type (countertop or over - range): This is also a qualitative variable. It classifies the microwave into distinct non - numerical categories.
• Power settings: This is a discrete quantitative variable. The number of power settings (e.g., 5, 10) is a countable number. It can take on distinct, separate values (you can't have a fraction of a power setting like \(2.5\) power settings in a practical sense for counting the number of settings).
• Color: Similar to brand and type, it is a qualitative variable as it represents different hues (e.g., black, white) without a numerical value for measurement in a quantitative way.

Answer:

power settings
