Question

Create a bar graph displaying copper plating amounts for four metals based on trial results. Which type of data should be used for representation?

a) Trial 1 data
b) Trial 2 data
c) Averaged results data
d) Interpolated data

Answer 1

For a bar graph showing copper plating amounts for metals based on multiple trials, the averaged results data is the most accurate to represent information clearly and reliably.

Step-by-step explanation:

To create a bar graph that displays copper plating amounts for four metals based on trial results, you should use the averaged results data.

Averaging the data from multiple trials helps to smooth out any anomalies or inconsistencies that might occur in a single trial, therefore providing a more reliable and accurate representation of the data. When constructing the bar graph, ensure that the axes are labeled clearly and utilize different colors or patterns to represent each metal, making the graph easy to understand.
