Worked Solution & Example Answer:The graph shows the body temperature of 60 people - Edexcel - GCSE Biology - Question 3 - 2012 - Paper 1
Step 1
Complete the sentence by putting a cross (✗) in the box next to your answer.
Answer
To determine the range in body temperature, we find the difference between the highest and lowest body temperatures shown in the graph. The highest temperature is 37.9°C and the lowest is 36.8°C. Therefore, the range is calculated as follows:
Thus, the correct answer is B. 1.1.
Step 2
State the type of variation, shown in the graph, that results in a normal distribution curve.
Answer
The type of variation shown in the graph, which results in a normal distribution curve, is called 'continuous variation'. This type of variation occurs when traits can take on a range of values rather than discrete categories.
