Question

minnie graphs the temperature over a 24-hour period. which type of graph should she use?
○ a discrete graph
○ a continuous graph
○ a bar graph
○ a histogram

Explanation:

To determine the appropriate graph for temperature over 24 hours, we analyze each option:

• A discrete graph is for distinct, separate data points (e.g., number of students per class), but temperature changes continuously over time, so this is incorrect.
• A continuous graph is suitable for data that changes smoothly over a continuous interval (like time). Temperature over 24 hours is a continuous variable (it can take any value within a range and changes continuously), so this is appropriate.
• A bar graph is used to compare discrete categories (e.g., sales of different products), not for showing continuous change over time, so this is incorrect.
• A histogram is used to show the distribution of a single variable (e.g., frequency of different temperature ranges), not to show how temperature changes over time, so this is incorrect.

Answer:

B. a continuous graph
