easy
A student collected data on daily high temperatures (in °C) over two weeks. Should they use a bar graph or a line graph to display this data? Justify your answer.

Solution

  1. 1
    Step 1: The data is numerical and recorded over time (14 consecutive days).
  2. 2
    Step 2: A line graph is best for showing how a numerical quantity changes over time, as it highlights trends and patterns.

Answer

A line graph, because it shows how temperature changes over consecutive days and reveals trends.
Line graphs are ideal for time-series data because the connected points make it easy to see increases, decreases, and overall trends.
