Question

Meteorology: One measure of average global temperature shows how each year varies from a base measure. The table shows results for several years.

Year	1958	1964	1965	1978	2002
Difference from Base	0.10°C	–0.17°C	–0.10°C	(1/50)°c	0.54°C

See the table and answer the following:

(a) Order the five years from coldest to warmest.

(b) In 1946, the average temperature varied by –0.030C from the base measure. Between which two years should 1946 fall when the years are ordered from coldest to warmest?

Answer 1

(i) 1964, 1965, 1978, 1958, 2002

(ii) 1946 should fall between 1965 and 1978
