(i) Explain two limitations of using only the range of the maximum temperatures to comment on the week’s weather variability.
(ii) Give three reasons why standard deviation is preferred over range when meteorologists compare the consistency of daily temperatures.
(iii) In not more than 80 words, summarise how the information provided by range and standard deviation would together give a more comprehensive picture of the temperature pattern.
