Average temperatures were recorded throughout a week starting from Saturday to Friday. The temperatures were 40, 30, 36, 37, 26, 32, and 27 degrees Celsius, respectively. Find the difference between the highest and lowest temperatures.
The difference between the highest and lowest values in a data set is known as the range. In this case, we’re calculating the range of temperatures in the week. We could write all of the temperatures in either ascending or descending order. However, it is clear from the list that the highest temperature is 40 degrees Celsius. The lowest temperature is 26 degrees Celsius. Whilst it is not relevant for this question, these occurred on Saturday and Wednesday, respectively.
In order to calculate the difference, we need to subtract 26 from 40. This is equal to 14. The difference between the highest and lowest temperatures throughout the week was 14 degrees Celsius.
