To show the change in temperature over a week, the most suitable graph would be a line graph. A line graph is ideal for representing data that changes over time, allowing you to easily see trends or patterns, such as an increase or decrease in temperature over several days.

Would you like further explanation on why a line graph is ideal?

Here are five related questions:

1. How does a line graph help visualize changes over time?
2. What situations would require a bar chart instead of a line graph?
3. Why would a pie chart be unsuitable for showing changes over time?
4. Can box plots be used to display data trends over time?
5. How would you interpret a line graph showing fluctuating temperatures?

Tip: Always choose the graph that matches the type of data and the message you want to convey—line graphs for trends, bar charts for comparisons, and pie charts for proportions.
