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 (X) in the box next to your answer.
Answer
To determine the range in body temperature, subtract the lowest temperature from the highest temperature in the data set. The highest temperature is 37.9°C and the lowest is 36.8°C. Therefore, the range is:
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 that results in a normal distribution curve is 'continuous variation'. This indicates that the body temperature can vary smoothly over a range, leading to the symmetrical bell-shaped curve characteristic of normal distributions.
