At a coastal meteorological station in Calabar, air temperature observations recorded at four specific intervals during a 24-hour cycle were $22.0^\circ\text{C}$ , $31.5^\circ\text{C}$ , $28.5^\circ\text{C}$ , and $24.0^\circ\text{C}$ . What is the mean temperature of these observations in $^\circ\text{C}$ ?

Answer: 26.5 °C

Answer

The mean temperature computed from the four observations is

26.5^\circ\text{C}

The mean temperature is calculated by summing all recorded values (

22.0 + 31.5 + 28.5 + 24.0 = 106.0^\circ\text{C}

) and dividing by the total number of observations (

4

), resulting in

26.5^\circ\text{C}

Step-by-Step Solution

Sum all four temperature values taken across the observation periods.

The total sum is

22.0^\circ\text{C} + 31.5^\circ\text{C} + 28.5^\circ\text{C} + 24.0^\circ\text{C} = 106.0^\circ\text{C}

Finding the arithmetic mean requires calculating the aggregate total of all recorded temperature data points.

Divide the calculated aggregate sum by the count of observation intervals.

\frac{106.0^\circ\text{C}}{4} = 26.5^\circ\text{C}

Dividing the sum by the sample size (

4

) yields the average temperature across the recorded intervals.
