Calculate the mean annual temperature.

• A. 17.5
• B. 18.5
• C. 19
• D. 21

Answer 1

The correct option is A 17.5

Mean Annual Temperature can be found out by dividing total sum of temperature of 12 months by total number of months, i.e. 12 months.

Mean Annual Temperature = $\frac{26+24+20+16+14+13+11+12+14+17+20+23}{12}$

Mean Annual temperature = $\frac{210}{12}$

Mean Annual temperature = 17.5 degree Celcius
