At a meteorological station in Jos, Nigeria, a weather observer records a maximum daily air temperature of $28.5^\circ\text{C}$ and a minimum daily air temperature of $17.5^\circ\text{C}$ using a Six's maximum and minimum thermometer. What is the mean daily temperature in $^\circ\text{C}$ ?

Answer: 23 °C

Answer

The mean daily temperature is

23.0^\circ\text{C}

The mean daily temperature is determined by taking the average of the daily maximum and minimum temperatures:

\frac{28.5^\circ\text{C} + 17.5^\circ\text{C}}{2} = 23.0^\circ\text{C}

Step-by-Step Solution

Sum the maximum daily temperature and minimum daily temperature recorded at the weather station.

28.5^\circ\text{C} + 17.5^\circ\text{C} = 46.0^\circ\text{C}

Finding the total combined temperature extreme values is the first step in calculating the arithmetic mean.

Divide the combined total temperature by 2.

\frac{46.0^\circ\text{C}}{2} = 23.0^\circ\text{C}

The mean daily temperature represents the average temperature over a 24-hour observation period.
