Learn the skill

Use the same months and units for both places. Subtract to compare temperatures. Keep track of whether a table covers all months or only a selection; a long-term average is not a forecast for a particular day.

Worked example

If January averages 5 C and July averages 21 C, their difference is 16 C. Without the other months, that does not necessarily establish the full annual temperature range.

Invented Monthly Averages

These fictional values represent averages over a 30-year period. City A: January 4 C, April 14 C, July 24 C, October 14 C. City B: January 14 C, April 16 C, July 18 C, October 16 C. No rainfall data or other months are provided.

5. What is needed to establish the range of all twelve monthly temperature averages? Only the population counts The averages for the eight unlisted months The spelling of the city names
