Answer :
To visually represent the monthly average temperatures in Gauteng province, a line graph would be the most suitable graphical display. This is because line graphs effectively show trends over time, making it easy to compare night and day temperatures across different months of the year.
Let's discuss in detail how to plot the data and display the graphical representation:
### Steps to Create the Graphical Display:
1. Identify Data:
- Months: January, February, March, April, May, June, July, August, September, October, November, December.
- Night Temperatures: 17.5°C, 17.3°C, 15.9°C, 12.5°C, 8.5°C, 5.5°C, 5.2°C, 8.2°C, 12.1°C, 14.6°C, 16°C, 17.1°C.
- Day Temperatures: 28.6°C, 26.8°C, 27.3°C, 24.5°C, 21.8°C, 20.1°C, 21.1°C, 23.4°C, 27.6°C, 26.3°C, 27.5°C, 28.4°C.
2. Plot the Graph:
- Create a line graph with the months on the x-axis and temperature on the y-axis.
- Plot two lines: one for night temperatures and one for day temperatures.
- Use different colors or markers to distinguish between the night and day temperature lines.
### Graphical Display:
Below is a textual representation of what the graph would typically look like.

```
### Description of the Graph:
- The x-axis represents the months of the year.
- The y-axis represents the temperatures in degrees Celsius (°C).
- The green line with bullets shows the average night temperatures for each month.
- The blue line with bullets shows the average day temperatures for each month.
- The legend helps differentiate between the night and day temperature lines.
This graphical display makes it easy to observe the trends in night and day temperatures over the course of the year in Gauteng province, highlighting temperature fluctuations and seasonal variations.
